GRATEFUL acknowledgement is made to the many observers who sent in records and to the Royal Society for the Protection of Birds, the Cambridge Bird Club, the Lowestoft Field Club and the Dingle Bird Club for allowing publication of records from their own reports. Particular acknowledgement is also made to C. G. D. Curtis for valuable help in the preparation of this report. All notes for 1964 should be sent to him at 100 Camden Road, Ipswich by the end of February next. All other correspondence in connection with the Bird Report should be sent to the Editor at Härtest Place, Bury St. Edmunds, telephone Härtest 224.
Separate copies of this report, as well as back numbers, can be obtained from the Editor, price 4/-. Survey of selected species : the same species as for 1963, viz Canada goose, magpie, collared dove, cuckoo, whinchat and lesser redpoll have again been selected for special survey in the county. Records of all species from the Stour and Waveney Valleys are particularly asked for. These areas are at present largely neglected ornithologically and it is suggested that some members might consider during the next year or two making a special study of either (or both) of these river Valleys in preference to the Suffolk coast which is at present almost " over-watched ". Attention is also drawn to two national surveys which are now being carried out. One, by the Nature Conservancy, deals with birds of prey ; the second is a B.T.O. survey of the status of the wryneck. INTRODUCTION :
A BRIEF REVIEW OF THE FAST YEAR
Preliminary comment was made in our last report on some of the more obvious results of the 1962-63 winter, one of the most severe that Britain has experienced for at least two hundred years.
468 Transactions of the Suffolk Naturalist*', Vol. 12, Part 6 At one time it seemed likely that some of our less-hardy birds vvould be almost wiped out, as had happened in the past under similar climatic conditions. Happily this did not prove to be the case ; while most species suffered to a greater or lesser extent, such normally tender birds as long-tailed tits, treecreepers, stonechats and bearded tits survived in encouraging numbers, showing perhaps no worse than a fifty per cent. drop. Heaviest mortality was among redwings, thrushes, water-rails, woodcock, green woodpeckers, wrens, goldcrests and kingfishers, the last three species being particularly hard hit. Dßring most of the year wrens were extremely scarce throughout West and central Suffolk and in many coastal localities also. At Aldeburgh, for instance, where nine wrens roosting together in one nest in January were found frozen to death, the species was thought to have been almost wiped out. Kingfishers and goldcrests suffered still more severely. Pied wagtails were also badly down in numbers everywhere and many gardens lacked their usual breeding pair. On the coast dunlins and redshanks, knots and sanderlings were found dead or dying along the tideline, while coots and moorhens, dabchicks and herons also suffered heavy casualties. With all the dykes and broads frozen over, ducks and grebes were concentrated in sheltered tidal Channels and estuaries and many parts of the coast were devoid of fowl for weeks. Grey geese were more widespread than usual, with small parties moving about in search of " open " feeding. Few of the geese went far inland. The first birds to succumb were, as always, the redwings which in many cases seemed too benumbed to take advantage of food provided for them. The fact that blackbirds, fieldfares, hedge sparrows and bullfinches, still in well-nourished condition, were also found dead, confirms the belief that the intense cold rather than lack of food was responsible for much of the mortality. However many species, particularly the Turdidae, must owe their survival to the abundance of berries and apples still hanging in hedges and orchards when the cold weather set in. At Härtest the unpicked crop on one large apple-tree sustained for about ten days a mixed flock consisting of forty-six fieldfares, fifty-five blackbirds, seventeen redwings, two song thrushes, two missel thrushes, eight chaflinches and a willow tit. At Brampton a green woodpecker also fed on fallen apples. Swans and ducks, usually associated only with coastal waters, were driven by the arctic conditions onto the unfrozen rivers of West Suffolk and whooper and Bewick swans, golden-eyes and parties of smews and goosanders were observed in the Stour Valley as far west as Long Melford. Others occurred on the rivers Lark and Little Ouse.

As usual under such climatic conditions, some of our less familiar birds were forced to seek food and shelter near human habitations. In January three woodcocks spent several days searching for food in a garden at St. Olaves ; all, unfortunately, were subsequently found dead. Another woodcock fed with starlings in a garden at Brampton where some days before a snipe had also been seen feeding on the lawn within a few yards of the house. At Minsmere the Warden saved the lives of a number of bitterns, water-rails and swans by bringing them indoors and releasing them again with the advent of the thaw in March. This thaw probably came only just in time to save many birds, notably the bearded tits which were probably about at the end of their tether. Although the summer weather was far from favourable, most species seem to have had a generally good breeding season and by the autumn wrens and green woodpeckers were beginning to reappear in many localities. Kingfishers, however, are still extremely scarce everywhere. Among summer visitors there was a further decrease in warblers, with blackcaps, whitethroats and chiffchaffs very much down in numbers throughout West Suffolk and locally in East Suffolk. There was a continued fall in the numbers of cuckoos everywhere, while whinchats and nightingales were thought to have decreased on both sides of the county. The stonechat, which came through the winter surprisingly well, had a fair season, with at least eight probable breeding pairs, but the woodlark's numbers continue to dwindle. Bitterns and bearded tits were present during the breeding season in most of their usual areas. No grey wagtails nests were reported, but a pair of black redstarts bred at Sizewell. Once again the marsh harrier bred only at Minsmere where eight young were reared, and for the first time since 1958 Montagu's harrier returned to breed in Suffolk. There were in fact two nests, one on each side of the county. One was successful and at least two young are known to have fledged from it. At the second nest, in West Suffolk, three eggs were incubated for six weeks, after which as they were evidently addled, they were removed for analysis, under licence from the Nature Conservancy. The result of this analysis showed traces of no fewer than five agricultural poisons, one of a strength of eight p.p.m. This was a most disappointing result, particularly as the farmer on whose land the harriers were breeding, sacrificed his hay crop in order that the birds might hatch undisturbed. Still more disappointing is the Minister of Agriculture's continued " head in the sand " attitude towards the use of poisonous
470 Transactions of the Suffolk Naturalists',
Vol. 12, Part 6
pesticides on farms and gardens. In the face of accumulating evidence that many of the chlorinated hydrocarbons used in agriculture and horticulture today are resulting in the deaths or infertility of a wide variety of species—birds of prey in particular— the Minister's " recommendation" that some of these poisons should only be used at certain times of the year and under certain conditions, will have earned little applause from those interested in the preservation of our wild life. Dßring 1963, Suffolk was again visited by a number of rare vagrants of which two were new species for the county. Both occurred in autumn, a Pallas' warbler at Walberswick on Nov. 16 and a dowitcher which occurred intermittently at Havergate between October and December. A green-winged teal, the American race of our common teal, was also identified at Butley in April. A broad-billed sandpiper, a pectoral sandpiper, two purple herons, an alpine swift and a red-headed bunting were also reported. Of particular interest was the occurrence at Minsmere in September of several spotted crakes, both adults and young. The species was recorded elsewhere in Britain at the same time. There were no hoopoe records and only one of quail, but late in the autumn Suffolk participated in quite a large " irruption " of waxwings, flocks of up to twenty-five occurring in many parts of the county. Shorelarks were also much more abundant than for many years. MIGRATION
Except for local food movements by geese and wood pigeons, very little hard-weather movement was noted anywhere during the Great Frost, nor did any marked migration take place when at last the frost broke on March 5. During the first few days of March lapwings, which had been entirely absent from the county for more than two months, began to return and small parties were coasting north at Minsmere and Aldeburgh, with emigration seawards on March 3/4 and 14/15. The usual emigration of starlings took place during March and April but very few redwings and fieldfares showed up during that period. Normal coasting by linnets and goldfinches took place at Aldeburgh and Minsmere from mid-March to the end of April and continued, in the case of the last species, tili about June 9. Emigration by chaffinches, larks, rooks and jackdaws, normally such a feature on the Suffolk coast in spring, was observed only on a very small scale. Despite the late spring, summer visitors were generally up to time and in fact the first wheatears and stone curlews were reported some days earlier than in 1962.

The first mflux of willow warblers, redstarts and nightingales took place on Apl. 12, with cuckoos, blackcaps and whitethroats arnving dunng the following week. There was a small passage of robins at Minsmere on Apl. 10 while whimbrels were going north both there and at Aldeburgh and Southwold between Apl 21 and May 14. As usual the first week in May brought a big rush of cuckoos, swifts and turtle doves. Only three pied flycatchers—all males—were recorded on spring passage, but fair numbers of black terns occurred on the coast between Apl. 23 and June 19, with one flock inland at Livermere on June 2. Late wheatears, probably Greenlanders were noted at Sudbourne on May 27. Wader migration was also late and rather protracted and there was apparent over-summering by green and wood sandpipers, dusky redshanks and greenshanks. Two examples of belated migration were observed at Härtest, a sedge warbler on June 8 and a sand-martin on June 27. Crossbills at Aldeburgh, Minsmere and elsewhere on the coast Irom late July onwards were probably part of the irruption that attected much of eastern Britain at that time. Coastal passage in autumn was rather thin, numbers of such species as wheatears, redstarts, pied flycatchers and wagtails in Sept. being much below normal. So were the numbers of finches particularly siskins, and tree sparrows Coming through in October' However garden warblers and lesser whitethroats were more plentiful thanusual. There was also a small passage of Continental robins at Walberswick and Minsmere in the last days of the month Very few goldcrests appeared, though firecrest numbers were about normal. There was a fair passage of wheatears, whinchats and phylloscopi at Sudbourne on Sept. 4, the first two species also being numerous about that date at Minsmere, where there was an influx of redstarts on bept. 13/14. For the second year running very little diurnal migration was noted over West Suffolk except for wheatears and whinchats. Among migrant waders on the coast both green and wood sandpipers were unusually plentiful in early August, so too were greenshanks spotted redshanks and curlew sandpipers A pectoral sandpiper-one of five in Britain at that time-visited Havergate in August and there was a broad-billed sandpiper at 1 v Minsmere on July 31. Watchers on the coast between Lowestoft and Aldeburgh recorded a spectacular movement northwards between Sept. 25 and 29 of skuas, terns and gannets. On the latter date three great skuas and between thirty to forty arctic skuas were seen off Minsmere and Walberswick, while sixty-five gannets were also
472 Transactions of the Suffolk Naturalists',
Vol. 12, Part 6
counted off Minsmere in three hours. This was probably an abnormal food movement due to the presence inshore of shoals of sprats or herrings. However a big shearwater and skua passage had also been noted elsewhere in Britain a little earlier. A number of swallows and house martins lingered on in various coastal and inland localities until well into November and a very late swift turncd up at Minsmere on Nov. 6. Late terns also occurred up to the end of October. A considerable southwards movement of kittiwakes took place in late November. On Nov. 23 some 4,000 were recorded off Southwold and Minsmere, with about 1,000 at Benacre next morning. Immigration by winter visitors was normal but unexciting. From early October to early November rather more starlings than usual were noted at Minsmere, where there was also a good coastal passage of goldfinches. 1,000 were counted going south on Oct. 11. At Lowestoft a day-long immigration of lapwings, starlings and sky-larks was recorded on Oct. 21. Fieldfares were crossing the coast at Orford in some numbers on Oct. 15 and small parties were noted in West Suffolk next day. Generally, however, very little daytime immigration was observed over inland Suffolk for the second year running. The first waxwings, forerunners of a bigger than usual irruption, were recorded at Aldeburgh on Oct. 20, with flocks or small parties at many coastal and some inland localities throughout the remaining months of the year.

474 Transactions of the Suffolk Natwalists,
Vol. 12, Part 6
In autumn, singles at Walberswick, Sept. 21 (DJP) and Havergate, Sept. 25 (RSPB), then up to ten in Oct. at Minsmere, one to three Nov. to mid-Dec., then twenty-five to thirty daily on sea, with at least one hundred present Dec. 22 (HEA, PJM). Approx similar numbers at Walberswick during Nov.-Dec. with c. eighty off Dunwich, Dec. 29 (GJJ, DJP). 5. Great crested grebe.—During severe weather early in year single birds occurred in Lowestoft harbour (EWCJ) and R. Blyth (GBGB) with twelve on R. Orwell (WHR), and others actually in Ipswich docks (CGDC). One at sea, Minsmere, May 5 (JELP). Breeding numbers were very much down and in some cases birds were absent from usual nesting areas. A few off-shore records from Walberswick and Minsmere between Aug. 10 and end of year (HEA, DJP). 6. Red-necked grebe.—One which frequented Lowestoft harbour between Jan. 17 and Feb. 14 was found dead on latter date (PB) ; two together Mar. 4, and two dead on beach in Feb. (CPB) ; one dead on beach, Apl. 9 (BJB). Single birds also at Minsmere, Jan. 8, Sept. 15/16 and Oct. 10 (HEA) and off Walberswick, Nov. 17 (JC, ADR).' 7. Slavonian grebe.—Only recorded from Havergate where single birds occurred Jan. 9/10 and Dec. 4/6 (RSPB). 9. Little grebe.—One to three during Jan. in Lowestoft harbour (many observers) and up to twenty in Ipswich docks in Feb. (CGDC, WHR) ; few breeding records were received but four pairs bred at Minsmere, a small increase due, perhaps, to elimination of coypus (HEA). 16. Manx shearwater.—One Aying north off Walberswick, Sept. 29 (GJJ) is the only record for the year. 26. Fulmar.—Noted in varying numbers on coast as far south as Aldeburgh in all months from Mar.

Highest numbers were twenty off Dunwich, Aug. 17 and the same number at Minsmere the following day (many observers). 27. Gannet.—The only spring records were of one to five offshore at Walberswick and Minsmere between Apl. 14 to 19 (HEA, RGB, DJP). In autumn greater numbers than usual on coast (chiefly at Walberswick and Minsmere) between July 17 and Nov. 24 (HEA, EFC, GBGB, RSH, GJJ, RVAM). Peak numbers were sixty-five Aying north in three hours (7 to 10 a.m.) on Sept. 29 (HEA). An im. bird off Minsmere, Dec. 22 (GJJ, DJP).

28. Cormorant.—Numbers varying between twenty-five to seventy on R. Blyth and c. eighty off Lowestoft in Feb. (GBGB, DJP) are considerably higher than those normally recorded. 29. Shag.—Single records during cold spell in Jan. and Feb. from Lowestoft (EWCJ, DJP), Shotley (MP) and in autumn from R. Orwell, Oct. 7 (MP) and Walberswick, Nov. 23 (DJP). A " probable " off-shore at Benacre, June 19 (CMV). 30. Heron.—As usual this species suffered severely in the cold winter of 1962/63. Breeding figures from some heronries in 1963 were : North Cove 21 nests Henham 6 Blackheath 22 Stutton 5 Brantham 6 Stoke by Nayland 11 (all per GBGB) Minsmere nil (HEA) Livermere 20 Eriswell 4 Brandon 2+ (AEV) While comparable figures for the previous year are not available in all cases it is evident that there has been a considerable fall, possibly as much as 50 per cent. 31. Purple heron.—An ad. at Minsmere from June 24 to Aug. 23 and an im. from Aug. 29 to Sept. 9 (HEA, G H , RSH, H H , PJM, et al). A purple heron, which the observers (GLC, ADR) believed to be immature, was also seen at Walberswick onjuly 28. 38. Bittern.—Although many must have succumbed during the " great frost ", a fair breeding stock seems to have survived in the county and birds were heard " booming " during the spring in at least five of their regulär localities (GBGB, EFC, JELP). Six pairs bred at Minsmere where " booming " was heard on June 21 (HEA). Inland records were : one caught alive, Ixworth, Jan. 19 (AAJ) and one seen there Sept. 9 (JC) ; one at Boxted in Feb. (PDK). 42. Spoonbill.—Two at Havergate during the period May 23 to 29 ( C G D C , RJP, W H R ) ; two at Minsmere, July 26 to Aug. 4 and on Aug. 9 and one there Aug. 6 (HEA).

Two or three at Havergate Apl. 7 to 26 and June 1 to 8 (RSPB). 50. Wigeon.—5,000 at Havergate on Jan. 6 but numbers soon feil away to a fevv score, building up again towards end of Feb. Late Nov. and Dec. numbers lower than in past years (RSPB). Thousands visiting stubbles in Iken area in early Feb. (JELP) and some 3,000 on Aldeburgh marshes early Mar. (EFC). 52. Pintail.—Düring Jan. and Feb. small numbers—about thirty—on R. Orwell (CGDC). Inland single birds on R. Lark Jan. 13 (CAEK) and R. Stour, Feb. 22 (CRP).

In autumn there were more reports and higher numbers than for some time. Up to tvventy occurred Lowestoft and Benacre in late Nov. (DJP), and about thirty at Aldeburgh in Dec. (EFC, JELP). There was considerable south passage off Walberswick and Minsmere between Oct. 20 and end of year, including a flock of c. 480 on Oct. 31 (HEA, DJP). 81. Barnacle goose.—A dead bird on Minsmere beach in Dec. (per HEA). 82. Canada goose.— Although this was one of the species included in the special survey, insufficient records came in to give a completely accurate picture of its county status. Füll records for 1964 are again asked for, particularly covering the Waveney and Stour Valleys, central and north-west Suffolk. On present evidence the species is obviously increasing and spreading. It is now widespread over most of north-west Suffolk and is increasing in the coastal belt. The position is confused by the number of feral birds. Breeding records for 1963 were : Heveningham probable (RSH) Sibton (DJP), Minsmere (HEA), R. Gipping (HEPS) and at Livermere, Culford and Redgrave and at many localities on Rs. Lark and Little Ouse. At least one colony on R. Stour (MM). Irregulär movement takes place by non-breeding birds (?) during Apl./May and Sept./Oct. 85. Whooper swan.—A flock of eighteen Bradwell, Jan 10 (ALB) ; two at Aldeburgh, Jan. 23 (EFC) and an im. at Ipswich docks, Apl. 4 to 14 (CGDC, WHR). Two at Havergate, Mar. 19 (RSPB). At Minsmere numbers up to seventeen on reserve or passing off-shore on various dates between Jan. 11 and Mar. 19. Single birds or small parties (never double figures) Nov. 23 to Dec. 29. A weak bird caught alive on Feb. 2 and kept in captivity tili released on Mar. 6, ate a large loaf of bread daily (HEA). In West Suffolk one or two were present on R. Lark, Jan. 27 to Feb. 17 (GMSE, CAEK, AEV). Three on R. Stour at Long Melford, Feb. 25 to Mar. 1 (MM, WHP). 86. Bewick's swan.—All records for early part of year came from Minsmere, Havergate and the Breckland rivers. At Minsmere two separate herds were present during Jan./Feb., with a total of up to fifty-six birds, of which nineteen died during frost (HEA, RSH). At Havergate there were two to four during Jan. with nine on Feb. 7 and seventeen on Mar. 27 (RSPB).

In West Suffolk a herd of between ten and twenty remained on the R. Lark at Icklingham from mid-Jan. to mid-Feb. Four also on Little Ouse at Santon Downham, Feb. 10 (CBC). One on R. Stour at Bures (per WHP). In autumn an ad. with mutes R. Aide, Sept. 13 to 15 (EFC) ; small numbers (maximum eleven) Benacre, Walberswick, Minsmere from Oct. to year's end (HEA, GD, DJP). 91. Buzzard.—Single birds were reported at Henham, Mar. 4 (PHTH), Benacre and Walberswick, Mar. 10 (DJP), Minsmere, Mar. 19, May 14 to 31, Aug. 11 to 24, Sept. 16, Oct. 6 (HEA).

Doubtless some of the Henham/Walberswick/Benacre/Minsmere records refer to the same bird. 92. Rough-legged buzzard.—Single birds at Walberswick on Feb. 3 (ADR, DJP) and Minsmere, Mar. 27 (HEA) and in west Suffolk at Lakenheath, Mar. 31 (CAEK). No autumn records. 93. Sparrow hawk.—No definite breeding records in the county and very few for the spring and summer, though a pair probably bred on the Breck (GMSE) and possibly in the Minsmere area— though not on the reserve (HEA) and at Tunstall (per WHP). An im. at Westleton, June 13 (GßGB) is early for passage bird. Single examples were recorded from Lackford, Jan. 27 (AEV, CAEK) and in Sept./Oct. from Badingham (PHTH), Holbrook (PRC), Playford (WHR), Ixworth (JC) and the Breck (NW). An im. in from sea, Ness Point, Sept. 14 (FCC). These records indicate a small autumn immigration. (InPeebleshireinlate Aug. many kestrels and some half dozen sparrow hawks were seen, obviously on passage through the hills (WHP). Winter records were single birds at Stoke-by-Nayland (JR), Kesgrave (PRC) and Walberswick (DJP). 99. Marsh harrier.—Bred only at Minsmere where two and a half pairs reared eight young. This area was also visited irregularly during breeding season by another male and female (HEA). These or others also seen occasionally during summer at Walberswick and Benacre (GBGB, J E L P , DJP, RV). Usual over-wintering birds in same area. Singles at Havergate during May and Aug./ Sept.

Quail.—One was present at Lakenheath throughout much of the winter 1962/63 but disappeared during the cold weather in Jan. (WR). 120. Water rail.—Hard hit by the severe weather, breeding numbers were very much down but by autumn it was once again widespread and in fair numbers. One, kept alive by the Warden at Minsmere, fed on dead sparrows, while others on the reserve ate dead coypus. At Boxted one was seen for several days in February feeding on a dead rabbit in a ditch (per WHP). 121. Spotted crake.—One seen at close ränge at Minsmere on Sept. 8 was apparently a young bird, while of three seen there four days later two appeared to be im.

486 Transactions of the Suffolk Naturalists', Vol. 12, Part 6 184. Ruff.—Records of this species during the year were practically confined to Minsmere and Havergate Reserves. The first birds arrived at the former locality on Mar. 13. Four males in füll breeding dress on May 17 were later joined by two females and up to six of both sexes remained throughout the summer though no breeding took place (HEA). This is the first definite "over-summering" in the county for a great many years. At Havergate six were noted on May 13, with a lone male on May 19 and two on June 6/7. There was a fair autumn migration at both reserves between July 19 and Sept. 30, with maximum thirty at Minsmere and c. eighteen at Havergate, where four late birds also occurred on Nov. 30 (HEA, RJP). Only other records were single birds at Walberswick, Aug. 31 (ADR) and Buss Creek, Sept. 1 (DJP). 185. Avocet.—The Havergate colony comprised fifty-five pairs. Ten to twelve pairs also bred at another site nearby, while another pair established itself at Minsmere and produced one Aying young, at least one other of the young having been eaten by a heron (HEA). The first birds arrived at Havergate, Mar. 12, and the last bird lingered there tili Dec. 30 (RSPB). Forty were seen at Iken, Aug. 28 (GBGB). 187.

194. Great skua.—Numbers at Minsmere and Walberswick between Sept. 6 and Nov. 23 were the highest so far recorded in the county, there being twenty records in all. Without doubt some, of these reports referred to the same bird or birds. Four were seen at Minsmere on Sept. 29 and three at Walberswick the same day. Two at Minsmere, Oct. 3 and two at Walberswick, Oct. 14. Single birds at Minsmere, on Sept. 6, 15 and 30 and Nov. 6, 19 and 23 ; at Walberswick on Oct. 6 and 20 and Easton on Nov. 23 (HEA, FKC, GJJ, DJP, PJM). 195.

Kittiwake.—Small numbers were present off Lowestoft, Benacre and Minsmere in Jan., then very few reported tili autumn except at breeding colony at Lowestoft and odd ads. at Minsmere and Aldeburgh in May/June (HEA, JELP). The Lowestoft colony contained seventeen occupied nests on June 21. As usual rough weather resulted in destruction of many nests and young and probably no more than four young reached Aying stage (EWCJ). Irregulär south ward passage on coast from mid-July to Nov., with a very large south movement past Covehithe, Southwold and Minsmere on Nov. 23/24. On former date several thousand kittiwakes were off Benacre (GBGB), and Southwold (DJP). At Covehithe and Minsmere next dav nearlv 4,000 were seen passing south (HEA, PJM, DJP).

Little owl.—Very few records, and same remarks as for previous species probably apply. 248. Long-eared owl.—Few reports came in. One at Stoke-byNayland on odd dates throughout the year (JR). Two to three pairs in Walberswick/Westleton area and two broods of young known (DJP). Few observed in usual Breck breeding area (WHP). 249. Short-eared owl.—Numbers on coast and inland were again very low, but three pairs bred Havergate (RJP). On Breck only odd birds seen in carrot fields in autumn where normally up to half score (WHP). 252. Nightjar.—Appears to be maintaining its numbers where habitat remains undisturbed. Eighteen breeding pairs Westleton/ Walberswick shows slight increase (DJP) while fifteen pairs Minsmere is slight decrease (HEA). Also recorded during summer at Foxhall, Purdis Heath, Brightwell and Hollesley (CDGC, PRC, WHR). Breckland numbers remain low (CBC, RV, WHP). 255.

Wryneck.—No summer records but Sept. brought what was probably quite a good passage of this species, single birds being identified at Benacre (FEM, DJP) and Aldeburgh (EFC) on Sept. 1, Walberwick on Sept. 2 (the bird being trapped) and Sept. 3 (AJG, CDH) and Lovvestoft, Sept. 2 to 5 (FEM), Minsmere Sept. 6 and 9 with two there next day (HEA) and finally one again at Walberswick on Sept 22 (GJJ).
271. Wood lark.—An apparent further decrease in most areas. One pair perhaps bred Walberswick (DJP), four pairs—a decrease of two—at Minsmere (HEA) and one pair Sutton (CGDC, PRC) with scattered records elsewhere in coastal belt in spring and autumn.
273. Shore lark.—There were more records and higher numbers of this species than in any year since 1953. Between Jan. 13 and Mar. 9 a flock of eighteen/nineteen was present in the Blythburgh area, with smaller numbers (finally one) there until Apl. 15 (GBGB, RGB, DJP). First autumn record was one at Walberswick, Oct. 27 (GJJ). At Minsmere, one Nov. 2/9, with five Nov. 10 rising to fourteen in early Dec. Eight still there at end of year (HEA). A flock of eighteen at Walberswick between Nov. 16 to Dec. 5 and six at Lowestoft Dec. 12 (DJP). Single birds CoVehithe, Nov. 11 (GLC) and Blythburgh, Dec. 28 (DJP)
274.
Swallow
Both species lingered later than usual,
276. House martinj the last swallow at Lovvestoft until Nov. 28 (EWCJ) and the last martin at Dunwich until Nov. 30 (DJP). House martins were also reported at Edwardstone, Nov. 16 (WHP), St. Olaves, Nov. 19 (FWRL), Oulton Broad (RSB) and Felixstowe (HRB) Nov. 20, and Minsmere, Nov. 23 (HEA).

281. Hooded crow.—Numbers during the cold weather were, as was to be expected, rather higher than during recent years. Fifteen to twenty were present in the Benacre area in Feb. (DJP, WHR) with two/six at Havergate and two or three on the R. Orwell in Jan./Feb. (RSPB, CGDC, WHR). Last at Minsmere, Apl. 24 (HEA). Only winter records were one Minsmere and two to four Havergate early Nov. An inland record from Berners Heath, Mar. 31 (CAEK). 284. Magpie.—Opinions on the status of this species in Suffolk vary widely. It is thought common, even increasing, at Henham (S), Playford (CGDC), Holbrook (PRC) and Aldeburgh (EFC) but absent from Brampton (BAC), scarce Brandeston (JRLP) and notably decreased during past ten years at Badingham (PHTH). Six pairs bred—two successfully—at Minsmere (HEA, PJM). Only one record from Easton (GBGB). Also bred Kesgrave (PRC, WHR). On Apl. 8, Single pairs seen at Rendlesham, Friston, Needham Market and Long Melford (WHP). In most parts of West Suffolk it is definitely decreasing. At Härtest where five years ago several pairs bred, none was seen during 1963. Elsewhere pairs or singles were recorded at Gt. Glemham, Market Weston and Glemsford (WHP). 294. Long-tailed tit.—General opinion on this species was that it had survived the severe winter surprisingly well throughout the county (many observers). 295. Bearded tit.—Although the hard winter of 1962/63 undoubtedly resulted in a heavy mortality among this species, there was no complete " wipe-out " as had happened under similar climatic conditions in the past. Numbers at Minsmere decreased steadily during Jan. and Feb. and immediately after the thaw only ten birds could be found on the reserve. Final breeding population, however, was probably eighteen to twenty pairs (about half that of 1962). A good breeding season followed, with some pairs apparently triple-brooded. Attempted irruption was again noted in Sept. and Oct. (HEA). At Walberswick c. twenty-five pairs bred—again a decrease of about 50%—and emigration was noted from Sept. 10 (DJP). Breeding was also confirmed at two other old sites but was doubtful at two more (GBGB, EFC). A number of birds at Butley in Oct. (JW). In West Suffolk four or five were observed at Stallode Wash on Feb. 5 (AEV). 298. Tree creeper.—Probably much reduced, if not totally wiped out, in some areas (S, GBGB) as a result of severe cold but in others numbers during the year were well maintained (JELP, HEA, WHP). Insufficient records were sent in to give.a balanced picture.

299. Wren.—Obviously suffered very severely indeed during the cold vveather of 1962/63 and was almost wiped out throughout much of the county. On the coast survived well here and there, e.g., Minsmere (HEA) but believed down 80% at Southwold (GBGB). However, by end of year numbers were building up again in many areas and by spring 1964 it was again widespread though still in smaller numbers than before cold spell. 300. Dipper.—There was one unconfirmed, but believed reliable, record during the winter 1962/63 from the R. Deben (per WHP). 302. Fieldfare.—One at Lakenheath, July 21, with up to five in same area in mid-June (WR) may indicate " over-summering " . 304. Redwing.—First noted at Lowestoft, Oct. 14 ( L F C ) with westward passage through West Suffolk next day (WHP). Numbers generally very much below average everywhere (many observers). 307. R i n g ouzel.—First recorded at Minsmere, Apl. 17 (as last year) with two on Apl. 28 (HEA, P J M ) and two next day at Hinton (PM). Single birds—both males—Christchurch Park, Ipswich, May 3 ( C D G C , WHR) and Thorpeness, May 4 (EFC). First in autumn at ! horington, Sept. 11 (RSH) and one, two and two at Walberswick on Nov. 2, 3 and 4 ( F K C , G J J , DJP). 317. Stonechat.—At least nine or ten pairs bred on coast, comparing well with previous year (HEA, G B G B , BAC, PRC, WHR, I'JM) but once again no breeding record, in fact few records at all, from Breckland where this species, once so plentiful there, seems to liave faded out. 318. Whinchat.—Like most wasteland birds the whinchat has been slowly decreasing as a breeding species for some time. 1963 saw a further decline in most areas, e.g., Walberswick/Blythburgh five pairs against eleven in 1960, and eight in 1962 (DJP). Breeding also at Westleton, two pairs (BAC, E M G ) , Minsmere four pairs, a decrease (HEA) and Aldeburgh, four pairs (EFC). Still breeds locally in the Breck but is probably decreasing there also as the forests grow up. 321. Black redstart.—A pair bred at Sizewell atomic S t a t i o n (HEA). A small spring passage at Walberswick and Minsmere between Mar. 30 to May 26 (HEA, P J M , DJP). One at Aldeburgh Oct. 19 to 26 (EFC).

322. Nightingale.—Breeding numbers vvere down in many areas. At Shotley numbers down to nil from ten pairs twelve years ago (MP). 324.
Bluethroat.—One Minsmere, Sept. 3 (PR).
357. Wood warbler.—A male singing Minsmere, May 19 to 26 (HEA) and others at Blythburgh and Walberswick between May 25 to June 6. There was no known nest in the area but a juv. was trapped there Aug. 1 (DJP). One at Minsmere, Aug. 15 (HEA). 364. Goldcrest.—Wintering birds were evidently hard hit by the severe cold and only a few—returning migrants ?—were recorded here and there in Mar. and Apl. However, four pairs bred at Minsmere (HEA) and there were autumn and winter records from Kesgrave (PRC) and Darmsden (JV). 365. Firecrest.—Only recorded from Minsmere where Single birds occurred on passage Apl. 9, 17 and 18 and Oct. 26, 29 and 30 with two on Nov. 1 (HEA). 368. Pied flycatcher.—Single males at Havergate, Apl. 27 (RJP), Aldeburgh, May 4 (EFC) and Walberswick, May 9 (JELP) were only spring birds recorded. A rather modest autumn passage on coast between Aug. 10 and Sept. 24 (HEA, BAC, RSH, DJP, JELP). 371. Hedge sparrow.—A small passage along shore, Minsmere, Oct. 4 to 21 (HEA) and at Havergate in Mar./Apl. and Nov. (RJP). 379. Water pipit.—One Buss Creek, Apl. 5 (RSH) ; Minsmere, Nov. 22 (HEA).

380. White wagtail.—Only reported from Minsmere where one Mar. 19 and two Apl. 4 (HEA). 381. Grey wagtail.—Another species evidently hard hit by the cold winter. There were no summer records from any of its usual haunts. A few passage birds noted on coast from Mar. 10 (CDGC, WHR) to Apl. 21 (RGB) and from Sept. 23 (HEA) to Oct. 21 (PRC). 382. Blue-headed wagtail.—A male at Southwold, May 6 (GBGB).

383. Waxwing.—In common with much of eastern England, Suffolk was visited during the winter of 1963/64 bv a considerable number of waxwings. T h e first party of seven reached Aldeburgh on Oct. 20 and thesc numbers increased to twenty by Nov. 19. Two to five remained throughout Dec. (EFC). Seven more visited Minsmere on Nov. 14 (HEA, PJM). At Felixstowe and Walton two to seven were reported between Nov. 23 to Dec. 7 (JBP) with about twenty at Trimley, Dec. 9 (HRB). U p to twenty-five in north Lowestoft during Dec. (FCC, N H , E W C j , HE], K L M , EAS) with same number feeding on apples at Oulton Broad, Dec. 15 (JGW). Small numbers also occurred in West Suffolk during Dec. 384. Great grey shrike.—Two at Minsmere in Jan. (HEA, PJM) and in West Suffolk one at Tuddenham, Feb. 17 (CAEK) and one at Barton Mills, Mar. 10 (RV). Single birds in autumn and winter all in the Walberswick Westleton, Blythburgh, Minsmere area between Oct. 19—arriving from sea—and end of year (HEA, PJM, DJP). 386.
Woodchat shrike.—One at Minsmere on June 8 (MF).
388. Red-backed shrike.—Few records of this species were sent in. Twelve pairs—a slight decrease—bred at Walberswick (DJP) and nine pairs, also a decrease, at Minsmere. Here, in one nest four out of five eggs failed to hatch and analysis shovved traces of D D T and chlordane. In another nest three out of five eggs did not hatch (HEA). This species is also decreasing on the Breck, there being fewer pairs everywhere than say ten vears ago (CBC). 391. Hawfinch. Recorded at : Minsmere (HEA), and Kesgrave ( C G D C , WHR). In West Suffolk small recorded during cold weather at Herringswell (CAEK), (RCM, ORM) Risby, Barrow and Fornham St. Martin
Playford numbers Culford (WHP).
394. Siskin.—Small numbers during cold weather and up to end of Apl. on both sides of county. A very small autumn migration. This species now summers on Breck and in some localities on coast but actual breeding has vet to be proved. 397. Lesser redpoll.—Possibly increasing owing to extension of afforestation but was also probably overlooked in the past. Breeding season records for 1963 were : Dunwich (GBGB), Westleton (BAC), Walberswick, where juvs. also trapped late July (DJP), Minsmere, three pairs (HEA, PJM), Aldeburgh, twelve nests found (EFC) and Purdis Heath (PRC).

This species is also breeding widely and evidently increasing on Breck, where flocks of fifty at times in winter (CAEK, DMB, WHP). Winter records from Brandeston (JELP), Foxhall, where c. eighty (GD), Badingham, rare (PHTH) and south-west Suffolk (WHP). A thin coastal passage at Walberswick and Minsmere in Oct. (HEA, PJM, DJP). Mealy redpoll.—Three/four Minsmere, Apl. 1 to 10 (HEA) ; one Westleton, Apl. 7 (RSH) and Apl. 22 (BAC). Four at Lackford in Dec. (PBL). 401. Bullfinch.—Although many succumbed during the cold winter, this species is still widespread and in orchard areas almost abundant. 404. Crossbill.—Reported from many areas, apart from usual breeding localities, throughout much of the year, indicating a " stay-over " from the irruption of 1962. Small numbers, adults and young, St. Olaves in summer (FWRL) and at Walberswick (RSH) and Aldeburgh (EFC) between Jan. to Mar. Also small numbers irregularly at Blythburgh, Walberswick and Minsmere between Apl. 22 and Sept. 3 (HEA, JG, PJM, DJP) but forty-six and forty-one at respectively, Blythburgh and Minsmere on June 2 (HEA, DJP). An ad. male and three juvs. Benacre, early June (GBGB). The autumn irruption, which affected eastern Britain, was probably responsible for one bird at Oulton Broad, Aug. 6 (per HEJ), five at Aldeburgh, July 30/31 (EFC) and two and five on shore at Minsmere, Aug. 30/31 (HEA). A few at Aldeburgh in autumn. In north-west Suffolk good numbers were reported from the Breck and neighbourhood during spring and summer (GMSE, CAEK, WHP, AEV) but there were no records from central or south-west Suffolk. 408. Brambling.—Generally small numbers during cold spell but up to 250 at special feeding points at Minsmere in Feb. (HEA) and 150 at Havergate during same month (RJP). Very few indeed in autumn and winter (many observers). 413. Red-headed bunting.—An adult male trapped at Minsmere showed little abrasion on wings, none on tail, and was very wild (HEA).
