According to bird count leader Jayne Lesley, “It was an outstanding count day for all groups, with lots of Yellow Warblers and Warbling Vireos, a nice assortment of less common Warblers, including Black-throated Gray, Hermit, Nashville, Wilson’s, and Townsend’s. Also spring migrants – Western Wood Peewee, Swainson’s Thrush, Western Kingbirds, Lazuli Bunting; summer breeders – Yellow-breasted Chats, Black-headed Grosbeak, Western Tanager, Bell’s Vireo, and Swallows (including hundreds of nesting Cliff Swallows under the freeway bridge). All that, plus lingering ducks, shorebirds, Pipits, White- and Golden-crowned Sparrows…and an American Bittern.”
The featured image of an American Bittern was found on The Cornell Lab of Ornithology All About Birds website and was taken by Brian Sullivan. They are a member of the heron family and are between a Green Heron and Great Blue Heron in size.
The above image of a Swainson’s Thrush was also found on The Cornell Lab of Ornithology All About Birds website and was taken by Blair Bernson. Swainson’s Thrushes on the Pacific Coast are “Russet-backed” as opposed to “Olive-backed” like those found elsewhere in North America.
