Recent survey work in Rocky Mtn. N.P. has yielded American three-toed woodpeckers (ATTW) as the most detected Picoides species so far during point counts this spring. Drumming has been the best detection method for individual especially in the first couple of hours after sunrise. I detected three individuals on 5/28 along the trail leading from Bear Lake to Bierstadt Lake in areas of insect-killed conifers. Almost any area of dying or dead trees is worth checking, especially looking for ATTW sign (trees with bark flaked off and piled around the base of the trunk).
