(Lola Allen Hammers) May 18. The Willam Section went to Tilden Park for the morning. It was a beautiful fresh, sunny morning and all the birds were singing. Just east of the Spruce St. Reservoir on the road which goes to the bottom of the canyon we found a Jayuli, Bentwing singing. We had excellent views of it; also of the Anna Hummingbird which came back over and over again to the same perch; Dnail were giving the guard whistle. Spotted Towhees, Brown Towhees, Nuttall Sparrow, Gb. Goldfinches, Purple Finches and Linnets, Paleolates Warbler. At the bottom of the canyon There were many birds in the trees along the stream. Paleolates Warblers were in conflict (bird males, our female?), House Wren, Warbling Vireos, Juncoes, Bush-tits, Sago's Wren, Song Sparrows, Western Flycatcher, Grosbeaks. 7 Buzzards; sailed over on set wings. We went down to the lake which has been dammed and is bordered with willows. One Yellow Warbler and two Tolemites and many Paleolates and Luscent warblers were heard and a Black Phoebe. One Western Tanager, caused a great thrill. Blue Sisters were heard frequently and both Jays were seen. Also Titmouse, Wrentit, Russet-backed Thrush and a Wood Bower was heard. Still no Hutton Vireos.
