Résumé :	A new breeding area for Kruper's Nuthatch (Sib a krueperi Pelzeln, 1863) was discovered in the Ak Mountains of Yozgat province of Inner Anatolia in pure Scots Pine (Pious silvestris) woodland. The average bird density was 1.23+/-0.85 individuals/km(2). The Habitat Suitability Index (HSI) was applied for altitude and habitat characteristics of Scots Pine within a raster of 500 x 500 in, and, based on this, a model distribution map was prepared using a Geographic Information System (GIS). Using a HIS-based threshold of more than 0.7 and the area of habitat, we calculated the population size of Kruper's Nuthatch in the Ak Mountains region as 558 individuals.
