This paper reports the results of bird observations at four study sites with many different habitats in the western Chentej-mountains (forest steppe, taiga) at the end of the spring-migration and the beginning of the breeding time. Altogether 134 bird species were observed, about 107 of which are probably breeding birds. Additional birds were caught using 6 mist-nets. In this way 98 birds of 21 species were caught, measured, and ringed. Furthermore feathers have been collected (molting feathers and near two breeding places of Accipiter nisus).

The bird fauna of the larch forests shows a high species richness (108 species), but the abundances are often very low (for instance for woodpeckers, thrushes, tits).

Muscicapa griseisticta is a new record (possibly irregularly) as a migrating bird for Mongolia (11-6-1990 [i.e. June 11, 1990], Davaany Sörlög - three individuals in a willow-shrub near a railway).

We suppose that Gallinago megala, Perisoreus infaustus, Losucstella lanceolata, Turdus sibiricus, and Pyrrhula pyrrhula are regular breeders in the forest areas of the western Chentej. Aquila clanga, Grus grus lilfordi, Hirundapus caudacutus, Corvus frugilegus*, Cinclus cinclus, Prunella collaris*, Regulus regulus, Luscinia sibilans, Luscinia cuyne, Pinicula enucleator, Pyrrhula cineracea, and Emberiza rutila are possible breeders in this area, or have been observed breeding (*). Furthermore, Haliaeetus albicilla, Falco peregrinus, Prunella montanella, and Turdus naumanni were recorded.

We propose to organize a registration-catching-program for birds in the western Chentej. We recommend nature protection for the flood-plains of some rivers for example Onon and Eröö.
