Drab in appearance, but a great singer, the House Wren (Troglodytes aedon) is one of the most wide-spread species in the New World. You'll find him from Canada to Tierra del Fuego. House Wrens also occupy a very broad range of habitats - I see them in the high conifers and the desert scrub. This one makes his Winter home around Peck's Lake [Arizona], and he's foraging and chattering in a patch of low scrub brush in this sample. The full recording lasts 5 minutes or so, with the song changing constantly.
