Found Song Sparrows, Lutescent Warblers, Flickers, Brown and Spotted Towhees, Blue Jays, Bush-Wrens, Vergin Vireos, R-c. Knights, Wrentits and Bilocalated Warblers in abundance. At the end of Monmoud Road was a Tolmie Warbler in full song.

Flycatcher, several Fox Sparrows, a Hermit Thrush, a pair of Titmice and several Juncos, and our 23 quail. The titmice are building in the lorn box on the fence post and a pair of lutescent warblers are building on a shelf in the bank at the east end of the Terrace. The female was gathering bark from the spiraea in front of the dining room window. Would come two or three times, taking a beak full of bark shreds each time, the male following her about, but not assisting. Then she would fly away with the male and feed in the oaks on near the ground for ten or more minutes. Then back again to the spiraea. Male did not sing. Saw female got's meet with bark at 7:45, 46, 47; 7:57, 58; 8:10, 8:11 - Did not match - 8:45, 46; 9:15; 9:40; 9:42, 9:45, 9:51. From 9:48 male was singing and driving away another male.
