I shot this Bewick's Wren last weekend in the Paton's yard in Patagonia, AZ. It's famous for hummingbirds, but none were around that afternoon. This bird was foraging on the ground flipping over leaves before it hopped up on the base of this tree. The Bewick's Wren song is highly variable. Young males learn their song from nearby territorial males, not their father. The unique song he develops in his first two months will be his for life.
