Plain Titmouse, Bush tit, Russet backed Thrush, Western Bluebird. A large flock of Cedar Waxwings was seen in Berkeley feeding on cherries in its Wilson garden. 41 Species. may 8th. Drove with James & Jannie and Miss Force to Vallejo, Napa, Sonoma, San Rafael. A beautiful day- may 9th. Weather still beautiful. Spent day in the garden - Russet- backed Thrushes in full song. At 8 a.m. Mrs. Parsons called me up to tell me they had a Hummingbird with a broken wing. I went down, caught the hummer which could not rise from the porch floor where it had fallen. Pelt it on the nest which contained one young bird and returned home for my glasses and magnifying glass. When I returned I found she had tried again to fly and had fallen on the ground. On examination I found her left foot and left ring were tangled in a mass of greasy cobweb (blue cord?) too strong for her to break. A number of tail feathers had been pulled out in her struggle to free herself. She lay quietly in my hand while we removed the web and washed the oil off with alcohol. After half an hour's rest on the nest she went about her duties as usual.
