The first note heard in the morning was the "Kek-kek-kek" of a Cooper Hawk. The next the song of the Hermit Thrush repeated over and over at different pitches. Later the Fox Sparrow. For some time I have heard a "k-k-k-k-k k-k-k-k-k" the second lower in pitch, in woods east of house. Is it another hawk call? Ruby- or Keight singing. judging from call notes the W. Flycatcher has a mate, west of house. P.M. Several 4-c sp. (moulting) at pool. April 1. Beautiful day. I heard the Cooper Hawk several times, and feel pretty sure he gives both calls (Mar. 31). At 4 p.m. Anderson Warblers were singing in oaks north east of house. April 2. At dawn the Lutescent Warbler was first to begin singing. Then the Hermit Thrush. I counted and found he sang his phrase 93 times with no breath. Counting two phrases to a song that would be 46 songs but there was no break between. At 9 a.m. a House Wren was singing near bottom of canyon (heard from N.W. porch). Many Aud. Warblers singing. Brown Towhee picking up food on pavement above house. Large flock Bushtits. Lutescent W (Feb. 21) sings from perch higher above road. No. 2. (Mar. 27) April 3. Hermit Thrush singing at dawn. Apr. 4. Hamilton Canyon: A flock of Aud. W. in acacias sp.
