Taxonomy
The Carolina Chickadee was first described by the ornithologist William Brewster in 1883. It was named after Carolina, the historical region of the Carolinas, where the bird was first encountered. It is part of the Poecile genus, which includes chickadees and other tits and titmice. The genus name Poecile is derived from the Greek word “poikilos”, meaning “variegated” or “marked”, referring to the bird’s distinctive plumage pattern.
The Carolina Chickadee is closely related to the Black-capped Chickadee and has been historically considered to be a subspecies of it, but genetic studies have since confirmed that the Carolina Chickadee is a separate species.
