I was at the Brickworks today and was hiking around the upper escarpment. I heard the loud and fast rat-tat-tat-tat! that you usually hear with pileated woodpeckers.
we looked around and i eventually saw the bird fly off and land on the dead tree that's on the front of the escarpment. it was roughly the size of a hairy woodpecker but it was missing the red crown and the size i associated with a pileated woodpecker.
it was overcast today so i couldn't ID the bird. if anyone sees it and can ID it, let me know.
