Audubon Warbler Nesting in Solano County, California

Online Full Text

On May 29, 1938, J. Duncan Graham and I were searching for gnatcatcher nests in the hills near an artficial lake two miles north of Cordelii, Solano County, California. While we were watching an adult robin which was scolding us vociferously from the close proximity of its nest, we noted another nest in the background in an adjacent tree. Mr. Graham climbed to it and a female Audubon Warbler (Dendroica auduboni) left the nest which held five young birds. These we judged were approximately five days old. The male, in full plumage, came to the nest repeatedly while we watched this interesting family.

The nest tree was a tall slender white oak, and the nest was about twenty-five feet up in a crotch formed by a limb branching from the main trunk. The nest was of very similar construction to those I have taken in the Sierra Nevada. It was composed of weed stems, and was plentifully lined with horse hairs and bird feathers. The young were gone on our, next visit (June 5) and the neat was taken and placed in my collection. I believe this is the first record of thll species nesting in the San Francisco Bay region.

Benicia, California, August 26, 1938
