Abstract Periodic inventory of species composition of fauna is one of the first tasks in the conservation of biodiversity. The North Ustyurt is one of the natural areas with a weak spatial-temporal study of herpetofauna and avifauna in the Western Kazakhstan. According to 2020 field studies and literary sources, a reliable habitation of one species of amphibians [European green toad Bufotes viridis (Laurenti, 1768)] and six reptile species [grey gecko Mediodactylus russowii (Strauch, 1887), takir agama Phrynocephalus helioscopus (Pallas, 1771), desert sand boa Eryx miliaris (Pallas, 1773), steppe ratsnake Elaphe dione (Pallas, 1773), blotched snake Elaphe sauromates (Pallas, 1814), Halys viper Gloydius halys (Pallas, 1776)]. As a result of the study of avifauna of late migratory and nomadic birds on the cliffs of the Doniztau and Zheltau mountains, 7 species of birds were identified that had not previously been recorded in the area [Tarsiger cyanurus, Ficedula parva red-breasted flycatcher, Eurasian blue tit Parus caeruleus, great tit Parus major, brambling Fringilla montifringilla, Eurasian siskin Carduelis spinus, reed oatmeal Emberiza schoeniclus]. In total, 33 species of birds found on the North Ustyurt. The materials obtained indicate a lack of study of herpetofauna and avifauna of the North Ustyurt and it is necessary to continue research here.
