July 12. Lazuli Bunting still singing near cottage Thrush songs much reduced. Grosbeaks Call occasionally but no song. Saw many last week in upper end of valley- July 13. Found Western Tanager feeding young at Ben Lound. Have found them each year in June near Walters Chergy or- Chard and have suspects they nested there July 18. Heard Western Martin at 4:209.m. July 20. Watched Vaux Swifts and learned their call - a high pitched squeaking sound. July 23. Drove along cliff north of Santa Cruz. One rock point off shore covered with Faral- Lond Cormorants and Gulls. One Heermann Gull seen. Farther north a bird flew out of a hole in the cliff - black with large white wing patches and orange feet. Body short (perhaps 10-12 in.) Wings longs. Bill moderately long. Several on water. Another bird flew north - plain gray above, lighter underneath. Looked like Brandering Tattler. The note of the group of birds was a high, prolonged note like the sound of wind singing through ropes or wires. The single bird utters a series of staccato notes, not quite as high, repeated rapidly.
