The fauna of vertebrate animals of the reserve is represented by 32 species of fish, 3 species of amphibians, 19 species of reptiles, 284 species of birds, 39 species of mammals.

The Central Asian frog (Rana asiatica) has ceased to occur in the last two decades, presumably as a result of displacement by the lake frog. It is listed in the Red Book of Kazakhstan.

The category of birds that disappeared from nesting in the second half of the twentieth century includes 4 species: loaf, osprey, corncrake, white-tailed piglet. Most of them, except the last one, are found here at the present time during the migration period. As a result of the natural processes of settlement in the Ile delta, 6 new species appeared at the nesting site during this period: ringed turtle dove, small turtle dove, red-bellied swallow, long-tailed shrike, great tit.

The key ones are the species that are important for the conservation of ecosystems. These include 20 breeding species: curly pelican, savka, white-eyed blackbird, burial ground, steppe kestrel, beauty bustard, saja (Red list of IUCN), pink pelican, spoonbill, golden eagle, white-tailed eagle, gray crane, whooper swan, black-bellied grouse, brown pigeon, owl, Ili saxaul jay (Red Book of Kazakhstan), white-winged woodpecker, gray tit, saxaul sparrow (endemic or close to them).
