We drove to Boulder Creek in the afternoon. We found every thing in blossom, Eugenias, Ceanothus, Flowering Crab-apple, Tamarisk, Mountain Ash and Lilacs. Also Baby Blue Eyes, Lavender, a few poppies (red) and California Poppies. Birds too were very abundant; Chickadees, juncos, Cassin and Warbling Wren, Black-throated Gray, Bulbuls and, Lutiscient warblers. No yellow warblers yet. Black-billed Throats and Olive-sided Flycatcher heard occasionally. Saw a pair of Allen Hummers and a Vaux Swift. Nothing fishers yet. April 23. Worked in the garden most of the time until we left at 3:30 p.m. for Berkeley. Beautiful weather - warm but partly overcast. Heard the Hermit Thrush. April 25. A Lazuli Bunting sang near the house. I saw a Cooper Hawk, circling just above the trees next the house. At 5 p.m. we took Prof. and Mrs. Wade-Garay across the two bridges - Immenseable flocks of Sandpipers on the sand at W. Berkeley and was the Toll Gate. Many Bonaparte Gulls. Cloudy most of the day.
