Black-throated Gray Warbler

On 27 May 2019 at the McLane Creek Nature Trail near Olympia, Erika and I were startled by a female Black-throated Gray Warbler. The bird collected objects from the ground along our path. Females are apparently entirely responsible for nest building and incubation. Males’ only contribution is to scold the female while she works. Nests are lined with feathers, grass fibers, and/or animal hair (Guzy and Lowther 2012). I don’t know what this warbler is gathering—perhaps dog hair, as plenty of dogs were being escorted through the park.
