After waiting for a few quiet, still minutes, he hitched up the trunk, making scratching sounds as he went, then suddenly let out a loud, startling trumpeted call. He attacked a small, thin dead stub, splitting it open, seemed to find nothing of interest there and moved further on up the trunk.<\/p>\n<p>He paused, clinging to the bark and staring at the trunk, turning his head only slightly one way, then another, then staring at the trunk again. He scratched the side of his head with a foot, then rubbed one cheek against the trunk. I thought it interesting how much time he \u2013 and other Pileated Woodpeckers I\u2019ve watched \u2013 spent apparently doing nothing. Just being there. Though I suspect he is doing something, and I just don\u2019t know what it is. I wondered if he could be listening for the sounds of insects under the bark?<\/p>\n<p>In a quick search, I did not find many references to this possibility. <span style=\"font-style:italic;\">T<\/span><span style=\"font-style:italic;\">he Birdwatcher\u2019s Companion to North American Birdlife<\/span> (by Christopher W. Leahy, page 384) notes, \u201cthere is some evidence . . . that woodpeckers can hear grubs and other wood-inhabiting insects moving in bark and trunks.\u201d<\/p>\n<p>And I found this more specific account on a <a href=\"http:\/\/www.tpwd.state.tx.us\/publications\/nonpwdpubs\/introducing_birds\/woodpeckers\/\" onclick=\"javascript:_gaq.push(['_trackEvent','outbound-article','www.tpwd.state.tx.us']);\">Texas Parks and Wildlife<\/a> website:<\/p>\n<p>\u201cThe evidence of [a woodpecker\u2019s excellent hearing] can be seen in the following account by a forester. \u2018I once saw a pileated woodpecker fly to a tough old hickory tree in which ants were using a little knothole as their entrance. The bird didn\u2019t drill in this obvious place. Instead, it circled the trunk, gently tapping, then pausing. Finally it proceeded to whack into the very heart of the ant nest \u2013 five feet below the knothole.\u2019<\/p>\n<p>\u201cWe do not know whether the bird heard the movements of the disturbed insects or was able to distinguish subtle differences in the tapping sound caused by the ants\u2019 hollowed-out tunnels and nest. However, we do know that something pinpointed the spot where further investigation was needed and, since the bird cannot boast x-ray vision, it is fairly safe to assume that the woodpecker\u2019s hearing played a major role in locating the ant nest.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This afternoon a male Pileated Woodpecker flew into the lower part of a tall pine on the edge of the woods.
