Most likely, several hundred pairs breed in Mittelgebirge habitats of the Pontic Mountains. The species is absent from the North German Plain, British Isles, Iberian Peninsula, and Mediterranean islands. In Italy, it is confined to the northernmost parts.

Researchers have discovered that the imperial woodpecker has slow climbing strides and a fast wing-flap rate compared with other woodpeckers. Owing to its close taxonomic relationship, and a similarity in appearance, to the ivory-billed woodpecker, it is sometimes called the "Mexican ivorybill", but this name is also used for the pale-billed woodpecker.
