We studied the breeding ecology of Krüper’s nuthatch Sitta krueperi (Pelzeln, 1863) in southern Anatolia between January 2000 and November 2003. the world distribution is mostly confined to coniferous forests in coastal Anatollia. Of 18 natural breeding cavities, 17 were located in coniferous trees, and the nest entrances were 11.8 ± 1.6 m (mean ± SE) above the ground, facing mostly an easterly direction. Data on breeding ecology of Krüper’s nuthatch were obtained from broods in artificial nest boxes in the forests. The nuthatchles used 16 of the 250 boxes. Main nest material was thin fragments of bark (57 ± 7.6%; n = 9). Egg laying in artificial nest boxes started on 24 March. Incubation lasted for 12–15 days (14.1 ± 0.2; n = 16) and the nestling period for 15–19 days (16.8 ± 0.3; n = 14). clutch size ranged from 4 to 7 eggs, mean 5.6 ± 0.2 eggs (n = 16). Overall breeding success was 71.6 ± 7.8%. Main food for the nestlings was coleoptera (33%) and Lepidoptera (14%) (n = 87).
