We are investigating large woodpecker foraging sign. Although furrows like the ones below can be created by Pileated Woodpeckers, we have never seen ones larger than 3 ft (except in eastern Arkansas.
We are interested in knowing if anyone has observed similar furrows greater than 3 feet in length particularly in the southeastern United States. Please email us with location; date; species of tree; length, width, and depth of furrows (accompanying pictures would be great). Please include a follow-up phone number in your email.
Steve’s Note: 8/3/07: Pileated woodpeckers have been observed creating or further excavating furrows like these.
