The northern flicker or common flicker (Colaptes auratus) is a medium-sized bird of the woodpecker family. It is native to most of North America, parts of Central America, Cuba, and the Cayman Islands, and is one of the few woodpecker species that migrate.
It closely resembles the black-backed woodpecker, which is also three-toed. Until recently, it was considered to be the same species as the Eurasian three-toed woodpecker, P. tridactylus. [6] Adults are black on the head, wings and rump, and white from the throat to the belly; the flanks are white with black bars.
An adult great spotted woodpecker is 20–24 cm (7.9–9.4 in) long, weighs 70–98 g (2.5–3.5 oz) and has a 34–39 cm (13–15 in) wingspan.

The following year, 1977, there was a significant increase in acorn production and a correlating decrease in non-breeding adults per unit ...

They all nest in holes that they excavate in trees, and the red-crowned woodpecker and the Hoffmann's woodpecker are unusual in that they sometimes enter their holes ...
