Miss Heding showed me an Album Hawing birds with in juncture - 2, 294. April 13. Clear with cold north wind. At early dawn, I heard one song phrase of the Thrasher; then one of Song Sparrows (4:50 a.m.). By 5 a.m. the Thrasher and Song Sparrows were singing continuously followed by the Spotted Towhee. Then a Hermit Thrush called several times and sang con- tinuously with fully twenty repetitions of its double phrases. Later the Wren-Tit, Bilestates and Telminie Warblers, Vigor's Wren were singing. At 8:15 a.m. the Lady Birds went to Cornell Hollow. The flowers were wonderful and hills that were dry at this time two years ago were lush with grass. But water was only just coming into leaf and sycamore trees were still bare. Before we entered the hills south of Livermore we saw orioles and Lewis Woodpeckers and many Mourning Doves. Fanchir or Thrushbirds and Saramanah Sparrows were abundant. We saw no Rock Wrens along the way and none at Cornell Hollow. On the way back we stopped at the little eroded valley where we found them two years ago and there we found a pair just starting a nest. Two years ago on this date the young birds were hatched (T.T. McCabe). The hole in which the nest was being built was near the top of the eroded bank and was only five inches or so deep and had a wide opening so that we could see the beginnings of the nest easily. The male perched near by; otherwise the female was at the nest. The Say Phoebe was seen near the bank also but frequently flew far
