Résumé :	As part of a bird mapping project at riparian and mountainous forest sites in the Republic of Adygeya, northwestern Russian Caucasus, in May 2004 we collected data on habitat use of the Middle Spotted Woodpecker subspecies Dendrocopos medius caucasicus. Our observations revealed that the subspecies utilises a variety of tree. stands with rough bark, including pure willow-poplar and alder woods. Furthermore, breeding was confirmed in beech-fir and polydominant broad-leaved forests containing large amounts of dead wood. We observed foraging birds up to the tree line at 1200 m. We assume, that the woodpecker inhabits all kinds of broad-leaved forests in the area that feature a sufficient amount of dead wood. These observations are in agreement with new findings from Central Europe, which contradict the traditional opinion of the Middle Spotted Woodpecker being a species strongly dependent on mature oak stands. Furthermore, we present data on population density and differences in voice compared to the nominate race. Using our density data, we calculate a new population estimate for the northwestern Caucasus of 8050 to 9200 breeding pairs.
