Observations ornithologiques dans le sud-ouest de la Mongolie. (Deuxième partie)

This article presents a list of ornithological observations, with notes, made during autumn 1992 and summer 1993, principaly in south-west Mongolia. The autumn observations show how important this area is for migrating or breeding raptors, such as; Black Vulture Aegypius monachus, Lammergeier Gypaetus barbatus, Steppe Eagle Aquila nipalensis, Golden Eagle Aquila chrysaetos, Upland Buzzard Buteo hemilasius, Rough-legged Buzzard Buteo lagopus, Long-legged Buzzard Buteo rufinus, Saker Falco cherrug and Peregrine Falco peregrinus. 10 species new to the Gobi National Park were recorded; Solitary Snipe Gallinago solitaria, Curlew Numenius arquata orientalis, Black-winged Stilt Himantopus himantopus, Kentish Plover Charadrius alexandrinus, Steppe Eagle Aquila nipalensis, Hen Harrier Circus cyaneus, Montagu's Harrier Circus pygargus, House Martin Delichon urbica, Pere David's Snow Finch Montifringilla davidiana and Chestnut Bunting Emberiza rutila, and during the same period 5 species were new for south-west Mongolia; Baikal Teal Anas formosa, Curlew Sandpiper Calidris ferruginea, Curlew Numenius arquata orientalis, Black-winged Stilt Himantopus himantopus and Chestnut Bunting Emberiza rutila. Observations made during summer 1994 confirmed the known breeding of Black-winged Stilt Himantopus himantopus as well as the importance of wetlands visited in this dry area for migrant birds. Observations made around the Mongolian capital, Ulan Bator, support those already published, mainly by German and Russian authors.
