A favorite of mine, the
Brown Creeper. I see this bird through my front window, as he hops up the trunk of a hackberry tree just outside. It's a tiny precious bird.
Widespread and generally abundant, but habitat loss and degradation is considered a threat to the species in some states, including Kentucky, Illinois, Indiana, Ohio, New Jersey, New York, Idaho, and Montana.

* The Brown Creeper bears an extremely close physical resemblance to the Eurasian Treecreeper and Short-toed Treecreeper, and was at one time considered the same species as the Eurasian Treecreeper. But studies of vocalizations, including experiments in which they do not respond to each other's songs, support recognition of three separate species.
* In Arizona, Brown Creeper nests often have two openings, one which serves as an entrance and the other as an exit. Entrances face downward and exits upward.
