This project is a series of research about birds and migratory birds of the Maltese islands. In the first part of this project I did some research about birds and specifically about migratory birds .Than I collected 7 types of different birds that migrate to the Maltese islands and did some research about them and also analyze their feather’s colour, analyze the height of their feet, analyze size of the beak and adoptions. In this project I am going to study these 7 birds closely. I am going to investigate them like Charles Darwin did but obviously on smaller scale. Charles Darwin Charles Robert Darwin, (12 February 1809 – 19 April 1882) was an English naturalist. He established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding .Charles Darwin did an intense research about species and organisms when he went on a “voyage” (The Voyage of the Beagle ) . Darwin came to understand that any population consists of organisms that are all slightly different from one another. Those organisms having a variation that gives them an advantage in staying alive long enough to successfully reproduce are the ones that pass on their traits more frequently to the next generation. Subsequently, their traits become more common and the population evolves. Darwin called this "descent with modification.”

Darwin’s Finches The term Darwin's Finches was first applied by Percy Lowe in 1936, and popularized in 1947 by David Lack in his book Darwin's Finches. The birds vary in size from 10 to 20 cm and weigh between 8 and 38 grams. The smallest are the warbler-finches and the largest is the Vegetarian Finch. The most important differences between species are in the size and shape of their beaks, and the beaks are highly adapted to different food sources. The birds are all dullcolored.

Information about birds : Bird , the only animal with feathers. All birds have feathers and most birds can fly. It is the possession of feathers, not the ability to fly, that distinguishes birds from other animals – some are flightless (like penguin , ostrich ) .The bird is an air-breathing animal that has a backbone and warm blood. It has two pairs of limbs- forelimbs adapted into wings for flying or swimming and hind legs for walking ,swimming ,perching or grasping .Although it hears well , the bird has no external ears. It reproduces by means of one or more hardshelled eggs , usually placed in a nest. Birds build their nests in a variety of places, including rocky ledges, trees, shrubs, or clumps of grass. Some fishes hollow out nests in the mud or gravel of pond bottoms or stream beds . How Do Birds Fly ? The bodies of birds are specially modified to give them the power of flight .Their bones are hollow to keep them light .Their bodies are also extremely lightweight, allowing them to glide and fly with the minimum of effort. For example , an eagle has a wing span of more than 3 metres and yet it weighs less than 4 kilograms. Birds also have air sacs linked to their lungs to give them extra oxygen as they flap their wings.

Migration Many birds and some insects ,fish and mammals, travel regulary from one location to another to accommodate themselves to environmental variations , or to their needs for certain changes in the environment. These periodic movements , which are often seasonal , are called migrations . Some animals apparently migrate for feeding purposes. As winter comes on .for example , many plant eating animals of the northern hemisphere go south where growing and insects are plentiful .Deer, elk, and some birds that spend summers high in the mountains spend winters at much lower levels. Some animals migrate to find conditions that are suitable for breeding. These conditions may include availability of nesting sites and materials and proper temperatures for breeding and caring for their young.

Merill The Blue Rock Thrush, the National bird of the Maltese Islands, is a solitary birds which resides in cliffs, especially the ones near the coast. The male's body is all blue with black wings and tail. The female is not colourful like the male is, as it is dark brown in colour. The Blue Rock Thrush feeds on worms, grasshoppers, lizards and skinks. The breeding season of this bird starts in March/April, when it is seen carrying twigs towards the cliffs, and ends in May/June. A female lays between 3 to 6 eggs and the pair may have 2 broods in the same season. In Malta this bird is widely known for its melodious song, echoing in the valleys. The male starts to sing from February and stops end of May. Telegraph poles, wires, trapping hides and rubble walls are amongst this birds favourite perches. Status and Distribution: The Blue Rock Thrush population in Malta is quite a strong one, with it being present along all the cliffs of western and northern coasts of mainland Malta. It is not usually recorded on the eastern coast of mainland Malta due to the lack of cliffs. It is also found breeding along the coasts of Gozo and Comino. When to See: All year round Where to See: Mainly near sea cliffs but may be also present in steep inland valleys or near buildings in ruins. A very good place to see the Blue Rock Thrush is the Majjistral Natural

Margun The Great Cormorant, is a widespread member of the cormorant family of seabirds. Its a large black bird, with a longish tail, thick, long bill and yellow throat-patch. It feeds on the sea, in estuaries, and on freshwater lakes and rivers. Northern birds migrate south and winter along any coast that is well-supplied with fish. The Great Cormorant can dive to considerable depths, but often feeds in shallow water. It frequently brings prey to the surface. A wide variety of fish are taken. The Great Cormorant is one of the few birds which can move its eyes, which assists in hunting. The Great Cormorant breeds mainly on coasts, nesting on cliffs or in trees, but also increasingly inland. 3-4 eggs are laid in a nest of seaweed or twigs. Many fishermen see in the Great Cormorant a competitor for fish. Because of this it was nearly hunted to extinction in the past. Thanks to conservation efforts its numbers increased. At the moment there are about 1,2 million birds in Europe. Chinese fishermen sometimes tie fishing line around the throats of cormorants, tight enough to prevent swallowing, and deploy them from small boats. The cormorants "eat" fish without being able to fully swallow them, and the fishermen are able to retrieve the fish simply by forcing open the cormorants' mouths, apparently engaging the regurgitation reflex. This traditional fishing method is known as Cormorant fishing.

Status: Regular autumn/winter migrant. In Malta the nominate species occurs, but the sub species lucidus/maroccanus of North Africa occured once when a single bird was recorded from Qawra on the 19th of November 2004. Mostly seen migrating in singles or in small flocks. An unusually large flock, in fact the largest ever recorded in Malta, was seen from Qawra on the 21st of February 2001. The flock was of 80 birds. Although it is not considered as a wintering bird in Malta, some birds do spend a part of the winter here. In winter 20092010, a group of 9 birds wintered at Salina. When to See: Mid-September till March. Where to See: Mostly seen from the coast, migrating offshore. Some use Salina, Ghadira and Simar Nature Reserves as feeding/resting spots. They often come into harbours aswell.

Pitirross: The Robin usually associated with Christmas time is a sign that Autumn migration is coming to an end. They have a distinctive orange red breast, small dark bill, olive brown uppersides and undersides and brown legs. Juveniles have dark plumage with red spots and brown fade body. The Robin arrives in large numbers in October and November. Many of these winter in Malta and therefore set up and defend their territory and keep other Robins out of it. It feeds from the ground searching for spiders, insects, worms, berries and seeds. Often comes to bird tables. It has a beautiful song and an tik-ik-ik-ik-ik alert call. Its population is secure and a Robin normally lives 3-5 years. Many Robins winter in the Mediterranean. Status: Very Common late autumn migrant and wintering species. When to See: Autumn migrants arrive in October-November and stay with us until March-April. A few also stay in summer in wooded areas with water present but never breed. Where to See: May be seen in any place with the presence of vegitation. One of the few birds that visit our bird tables.

Argett Abjad Little Egrets are lively and elegant white herons, always fun to watch. They have a black beak and and black legs. Their feet are distinctivley yellow and during breeding season they spread plumes of head, back and breast. Little Egrets wade in shallow water, sometimes belly-deep, often running around to stir fish around, making it easier for them to grasp with their long, sharp beaks. These birds nest in tree colonies, often with other heron species. Status and Distribution: A common heron. Seen mainly in Spring and Autumn. Many singles are seen in the reserves and many flocks are seen both in the reserves and from the coasts, often seen resting on small islets or large rocks. As a breeder, the Little Egret is very rare, having attampted breeding only once, in 2007 at Salina. A pair with a nest contaning 3 eggs tried to breed in June 2007 but one of the adults was shot by poachers and therefore the breeding attempt failed. In 2010 a pair bred again at Salina, this time raising successfully 4 young. When to See: Spring and Autumn. Some spend the summer. Where to See: Simar, Ghadira and Salina. May be seen flying from anywhere, especially from the coast.

Għasfur Ta’ San Martin The Common Kingfisher is a small sparrow-sized kingfisher that can be found across Europe, Asia and Northern Africa. It is resident in much of its range, but migrates from places where rivers freeze in winter. You'll find Common Kingfishers perched 3 to 6 feet above water with its bill pointing down as it searches for prey. It bobs its head when food is detected to gauge the distance, and then plunges steeply down to seize its prey usually no deeper than 19 inches below the surface. They eat mainly fish, but they'll also catch insects and crustaceans including shrimps.

Fjamingu The Greater Flamingo is a large bird and well-known to many people. It is tall, pink and white plumage with a down curved bill. It has pink legs and reveals black wings with crimson red in flight. In flight its pink neck is a key feature in identification especially if seen very far away. Feeds on invertebrates and algae by funneling its beak through shallow water. It breeds in several colonies around the Mediterranean with c 35,000 pairs mainly in Spain, Sardinia, France and Turkey. Juvenile birds are darker and more grey. Often seen in flocks. Status: The Greater Flamingo is scarce and irregular, mostly seen in singles or small flocks offshore. Some singles or couples rest at Ghadira Nature Reserve for some time. A single 1st year flamingo stayed at Ghadira from September 2008 till May 2009. On 6th November 2008 a 1st year Flamingo, carrying a ring from Sardegna was present at Salina. When to See: It is recorded in a number of different months, but mostly in September migrating along the coast. Where to See: Occasionally some individuals 1-2 spend some hours or days at Ghadira Nature Reserve where they feed. Other sites; Qawra, Salina and around the coast.

Kuċċarda A big long winged buzzard with a small head and a rather long tail with three dark bands. It has variable plumage patterns. The male has a grey head, Female has a brownish head and juvenile has a much whitish head with a yellow base at the bill. The Honey Buzzard migrates in flocks and is usually seen in the afternoons. They spend their winter in Africa south of the Sahara. Like many other birds of prey, the honey buzzard finds it difficult to fly over open sea difficult so they prefer to soar on rising air which occurs on land therefore their migratory routes concentrate over short sea crossings like Gibraltar, Sicily, Falsterbo(Sweden), Greece, Bosphorus(Turkey) and Malta. It likes eating Honey, wasps, bees, ants and other insects. Status: Common Autumn migrant in September till October and in Spring April till May. Mainly seen in the afternoon in flocks and occasionally roost in wooded areas and other undisturbed land. On a good day with favorable winds, numbers can reach to over 500 individuals. When to See: April/May and August till October. Where to See: During migration may be seen from anywhere. Amongst the best places in Autumn is Buskett where many Honey Buzzards are seen along with other raptors. A good place to see Honey Buzzard in Spring is Dwejra, Malta.

Actually the kingfishers actual colour is a murky brown colour. If you were to place the iridescent blue feather of the kingfisher into the shade, the colour changes to this brown colour. This is because when the kingfishers feathers are hit by the white light from the sun, the feathers only absorb the only absorb the blue frequency (wavelength) of light. As a result when the light reaches your eyes, the eyes register that the blue wavelength of light is missing, so we see the feathers as blue in the sun

This project was really helpful for me , it helped me to value more this precious organsims , they give life to the sky .Now I strongly disagree with hunting for birds , I feel that hunters are emptying our skies . I would like to thank my amazing biology teacher who helped me so much with this project . ď Š
