Birds - Audubon Warbler

A delightful flock of Audubon Warbler (Setophaga coronata ssp auduboni) swarmed through our yard today. This is kind of an unusual bird for our backyard, and is especially unusual in a flock. Audubon Warbler are supposedly a year-round resident here in the Pacific Northwest but, as far as I've seen, they are most common here during Spring and Fall migration.

Audubon Warblers are the western version of the Yellow-rumped Warbler. Warblers in general are a variable group of small perching birds that are small, vocal and insectivorous. Due to the difficulty in identifying Warblers, they are many times referred to as LBJ's (Little Brown Jobs).
