Dryocopus pileatus

3 mi. N Willow Creek, 700 ft., Humboldt Co., Calif.
Aug. 27 (cont.) Its position when drumming was at quite an angle with the vertical:
apparently it did not want to,
or could not, cling to the wood in the narrow scar; but the wood there was resonant & produced a loud, hollow sounding drumming.
There were several such scarred Ten Oaks in the vicinity, and just up slope from them, a slash area with many felled madrone trees & some dead snags. It was on the latter that the woodpeckers were first seen.
Finally, I climbed onto a large, firm Douglas Fir stump & stamped my heel several times on it. The 7 woodpecker left his drumming post immediately & flew m. o' digits on the opposite side of the trunk of a nearby tree. I stamped again & he flew to a still closer dead snag; but apparently recognizing me then as dangerous, he flew back toward the drum-ming site landing on a Douglas Fir trunk. I collected him at this point. He gave a shrill, but weak, scream as the shot hit him.
