| 摘 要： | The Middle East is an important contact zone for a considerable number of bird taxa from the western and eastern Palearctic and from the great Saharo-Sindian desert belt.Using WORLDMAP software,we analyzed the geographical distribution of secondary contact zones for parapatric species pairs of birds in the Middle East.We identified 56 species(29 species pairs)that make contact in the Middle East.The species pairs belong to three orders,i.e.Falconiformes,Piciformes,and Passeriformes.Almost half(46%)of these species pairs hybridize in their contact zones.Although contact zones occur over a large part of northern Middle East,spatially they were not evenly distributed.Contact zone richness was highest in the mountain ranges south of the Caspian Sea and the Caucasus.The hottest hotspots,where up to nine bird species pairs occur sympatrically,are situated in north-eastern Iran and Azerbaijan.We discuss the relevance of these hotspots for improving our understanding of the biogeography and evolution of the avifauna in the Middle East.
