1938 April 17. Easter, Berkeley. A very warm spring day. Lutecent Warblers give their alarm notes in certain parts of the garden. I heard one Audubon Warbler. No Hermit Thrush. Worms are beginning to eat the new foliage on the oats. A Purple Finch sang at 2 a.m. - nesting near? Sislin's head. Lutecent warblers are singing very better. April 18. Still warmer than yesterday. Spent the morning. Heard a Hermit Thrush early. Later the Black-headed Grosbeak was singing. About 8:15 a.m. A Tolew Warbler was very near, a Red-breasted Nuthatch also; and a House Wren investigated the Titmouse Box. Spent the morning with a class in Cordova's Park. So many birds singing. Only two winter visitors: Golden-crowned Sparrows (corns bright) and Cedar Waxwings. A Spotted Towhee gave a very peculiar song and syllabled, loud, clear - no suggestion of the usual song. List David, Annora Allen H. (an Allen was cheering a Calcutta Warbler); W. Flycatcher, Titmouse (quiet), Bushtit, Vesper Wren, Wren A., Robins Warbling Vireo, Lutecent and Calcutta Warbler, Ammott, Purple Finch, Grosbeak, Wk. Goldfinch, Brown Spotted Towhee, Song Sparrow. 208 species. Those checked were singing continuously
