A Chestnut-backed Chickadee (Poecile rufescens) pauses on a branch to ascertain the status of its neighbors. Close cousins of the Black-capped Chickadee, the songs of the Chestnut-backs, such as the familiar “chicka-de-de-de,” are not quite as distinct. Despite noticeable color differences and singing habits, the two birds nevertheless behave quite similarly, and can often be found together. This is especially true in the winter when they sometimes form mixed-species flocks with several other bird species.
