Site description. The Khosrov Reserve lies in a central part of southern Armenia. The terrain is rather complicated. The entire area is typically alpine, densely traversed by primary and side-gorges, high plateaus and inter-montane depressions, massive towering mountain ranges, volcanic expanses and isolated mountain peaks. Two alpine rivers, the Azat and Verdi, with tributaries and a small lake (0.3 ha) are within the IBA. The area extends over four landscape zones: desert/semi-desert, mountain steppe, woodland, and alpine and subalpine meadows, though much valuable high-altitude habitat (meadow steppe on plateaus and rocky areas) lies outside the reserve.
Key biodiversity. At least 156 species have been recorded and 76 of these have been proved to breed. An outstanding site for raptors, with at least 21 species breeding and three possibly breeding, including Aquila chrysaetos, A. pomarina, Circaetus gallicus, Accipiter brevipes and, uniquely in Armenia, a small relict population of Aegolius funereus. A colony of Apus melba in Azat Gorge numbers some 2,000 birds. Among other breeding birds are Dendrocopos medius, Oenanthe hispanica, Monticola saxatilis, M. solitarius and Bucanetes githagineus.
Trigger species. Caspian Snowcock (Tetraogallus caspius), Chukar (Alectoris chukar), Bearded Vulture (Gypaetus barbatus), Egyptian Vulture (Neophron percnopterus), Griffon Vulture (Gyps fulvus), Cinereous Vulture (Aegypius monachus), Long-legged Buzzard (Buteo rufinus), Eurasian Scops-owl (Otus scops), Eurasian Eagle-owl (Bubo bubo), European Bee-eater (Merops apiaster), Yellow-billed Chough (Pyrrhocorax graculus), Eastern Rock-nuthatch (Sitta tephronota), Wallcreeper (Tichodroma muraria), Blue Rock-thrush (Monticola solitarius), Alpine Accentor (Prunella collaris).
