p. insularis The brown-headed nuthatch (Sitta pusilla) is a small songbird endemic to pine forests throughout the Southeastern United States.

[2][3] Two recent studies assessing vocalizations in Bahama and continental nuthatch populations found important differences.

[8] Recent genetic assessments suggest some of the putatively non-breeding adults associated with these groups may actually breed with individuals in neighboring territories.

[13][14] This species sports a brown cap with narrow black eyeline and buff white cheeks, chin, and belly.

If heard or seen well, this species is virtually unmistakable in the wild, since it overlaps only with the very differently marked and larger red-breasted and white-breasted nuthatches.
