Willamette Valley, William L. Finley National Wildlife Refuge, Oregon
May 23, 9:10 a.m.
Sunrise at 5:37 a.m.
Acorn woodpeckers among the oak trees, coming and going, calling, and eventually one drums (0:47), though weakly, at the relatively slow rate of 16 beats/second.
Single calls might sound a bit like thhwaack; when two birds are calling, listen to how their individual voices differ. The call more befitting their clown-like faces is a laughing, two-syllable whack-a, whack-a (0:25).
Distant western meadowlark, European starlings, American goldfinches
