Banks 1957 Zonotrichia leucophrys nuttalli 6. 18 March S.W. corner Edwards Field, Berkeley, Alameda Co., Calif. minutes later I was singing + a was feeding on lawn. I gave trill. A dog came - one bird gave sharp alarm note, was seen on sloping part of wall (end of bleachers). This note is the call one typically heard when the birds are alarmed at a close danger. Last year it was given mainly when I was in the immediate area of the nest. It is a sharp "chirr", dropping a little but essentially 1 tone. Now, 2 min after dog left, both birds are gone. 22 March 1957 Between Fulton Street, between Dwight & Bancroft. A bird feeding + chipping in the lawn here, & sided street. Flew to bushes across street past EB MUD parking lot, back of small house. Athletic Field, Lower Section When I arrived a bird across street at 2214. Later I thought there may be 2 pairs near. Don't know. Right now a bird chipping near lower columns and big solar. This is a while, disappears a while. Another pair at upper end of this section. One on wall joined one on ground and both fed moving W. Can into other pair; once came back, are now with other birds. No chase involved.
