Dendrocopos pubescens
Mar 13. Berkeley, Alameda Co., Calif.
Noted woodpecker drumming on leafless maple tree
on Bancroft Way at noon.
Mar 26. Strawberry Canyon, Univ. Calif. Campus, Alameda Co., Calif.
9:00 clear calm morning. Heard woodpecker
drumming in oaks N of Strawberry Pool; bird gave
or whinny. About 9:15 a ♂ flew into dead willow
where creek enters culvert above pool. This ♂
drummed, usually on protruding pieces of dead
bark which provided better “sounding boards,”
as shown →
The bird also
foraged. Calls given were a sharp pick and
the whinny. After 3 minutes the bird gave
another whinny and flew downstream in a
direction leading slightly to south of the
streamcourse. Apparently this post marked
the eastern extent of this male's territory
(written from memory Mar 27).
Apr 2. 9:15 - noted ♂ actively foraging in elderberry, oak, willow
near dead alder on creek opposite Poetry Fawnhome.
Bird definitely ♂ gave whinny on two occasions – no
evidence of ♀.
