The Krüper's Nuthatch, Sitta krueperi, is a small nuthatch found in south east Europe and south-west Asia.
It occurs in Turkey, Georgia, Russia and on the Greek island of Lesvos.
It breeds from mid-March to late June in the Pinus brutia forests of Antalya, Turkey. The forage in pairs and when one bird finds food, calls for the other to join. Courtship includes ritual feeding of the female by the male. They nest in decayed cavities or woodpecker holes. Only the female incubates the egg while the male feeds it. Males fluff up their feathers and assume a hunched posture when defending their territory. Fledglings are often seen hanging from branches.
The name of this bird commemorates the German naturalist Theodor Johannes Krüper.
