same solemn procession that northern latitudes or landscapes further east experience. In large part, this is due to California’s Mediterranean climate, where the most stressful time of year is during our long, dry summer as opposed to an icy winter. However, a keen eye and an appreciation for shifts at an ecosystem level reveal major seasonal transitions beyond just shorter days and cooler temperatures.

WINTER BIRDS and Where to Find Them

One of the best indicators of seasonalit y in our region, especially at this time of year, is the local avifauna. By paying attention to which birds are and are not present in our yards, Gardens, and open spaces, we can build our seasonal fluency in southern California. For much of North America, winter is a season of sparrows. These seed eaters form large flocks across the continent and there are a few species that will be present in our Garden and your neighborhoods throughout the winter.

I WINTER BIRDS n southern California, the shift between seasons can be subtle. With freezing temperatures and snow limited to high elevations and an abundance of evergreen trees/shrubs in the dominant plant communities of the lower elevations (oak woodland, chaparral, coastal sage scrub, etc.), the arrival of fall and its transition into winter don’t seem to follow the

White-crowned Sparrow (Zonotrichia) – These large sparrows in the genus Zonotrichia are t ypical of that group in that they are relatively large-bodied and have long tails. Adults will have strong black and white patterning on their head, while juveniles will favor a reddish crown/eyeline combo. Being seed eaters, they are attracted to plants such as buckwheats (Eriogonum sp.), goldenrod (Solidago sp.), and other members of the sunflower family (Asteraceae). Look for them in the groundcover display near the Garden entrance, in the meadow, and around the Porter Trail. Ph

Fox Sparrow (Passerella iliaca) – A third winter sparrow that we are likely to encounter in the Garden, our neighborhoods, or in open spaces, is the Fox Sparrow. These are also large sparrows that sport a densely spotted breast. They prefer dense, thicketlike habitat, so places like the Meadow View, Porter Trail, or Woodland Trail, or even in the Canyon are good bets to spot this bird. They will likely be digging in the leaf litter, looking for insects and seeds to eat.

Golden-crowned Sparrow (Zonotrichia) – These cousins to the more-ubiquitous White-crowned Sparrow share the same body proportions, but have different plumage overall. Golden-crowneds are t ypically darker brown with a black and yellow pattern on their head. Juveniles will have less bold head patterning, but yellow should be present near the eye. They are a bit more shy than white-crowned sparrows and are more likely to be encountered on the Porter Trail and east slope of the Garden, also feeding on seeds. You may see them in mixed flocks with the Whiter crowned sparrows. Listen for their plaintive song that e ier chm is often transcribed as, “OOOh Deeear Meeeeee.” S n o: Ala
