A ♂ "buzzed" over and landed on top of a tall (15 ft) scrub oak bush which overlooks a brushy slope (coyote bush, thistle, poison hemlock. Approx. 20 min. later he began to sing from that perch; the song continued virtually uninterruptred for several minutes. (these details recopied from days journal). Jan. 12 8:00 AM. ♂ on top of tall coyote bush in same brush area as Jan 11. Later it sang as it flew slowly overhead. 10:00 AM. A ♂ lives at a Hutton's Vireo feeding in the top of coyote bush in a different brush patch than before. The vireo moved about, not necessarily in response to the attack, but remained the focal point of three subsequent dives. March 4 Strawberry Canyon, Alameda Co, Calif Sunny, warm, south facing oak-grass slope. One ♂ seen perching on highest twig of various species of bushes, which include Coast Live Oak & Elderberry. On one occasion it landed on lower coyote bush top, rather than taller poison oak stem. (Possible aversion to poison oaks). It seems to have several favorite perches scattered 20 or more feet apart.
