I've noticed recently at two different Mississauga parks (Riverwood; Rattray Marsh) that the Pileateds are very quiet when they hunt on dead ash trees. They listen, then shear off the bark in large bits, then eat. There is almost no hammering to get what they want. I've also noticed people walking right by them even though they are only a few yards/metres off the trails and up a trunk a few yards/metres probably because they are so quiet. I think people who do hear the noise may think it's just another Hairy/Downy. Certainly the people I pointed the birds out to recently were quite surprised, though pleased to see them.
Has anyone else noticed this or noticed what seems to be an increase in Pileated numbers over the past few years as the Ash trees die?
