The northern flicker (Colaptes auratus) is a medium-sized bird of the woodpecker family, Picidae. It is native to most of North America, parts of Central America, Cuba, and the Cayman Islands. Adults of this species are brown with black bars on the back and wings, with a mid- to large-sized northern flicker measuring 28 to 36 cm (11 to 14 in) in length and 42 to 54 cm (17 to 21 in) in wingspan. Its body mass can vary from 86 to 167 grams (3.0 to 5.9 oz). Northern flickers are partial migrants, with those that do migrate beginning their spring migration in early April and making their return between September and October. Individuals that breed farther north travel greater distances than their migratory southern conspecifics, often resulting in the convergence of northern and southern populations at wintering sites. This male northern flicker was photographed looking out from a nesting hole in a tree in Central Park, New York City.Photograph credit: Rhododendrites
