In the spring there are mass migrations of the Common Toad to the spawning sites. Young toads often are prey of adult toads and frogs (Pikulik, 1985). Sometimes the Common Toads are eaten by the Grass Snake (Natrix natrix) that is specialized on amphibians (Drobenkov, 1995). Toads also are eaten by polecats, otters, and American and European minks. The latter eat only the belly part of toads because of the numerous toxic glands on the back. Quite often this species is eaten by some birds: Buteo buteo, Aquila pomarina, Athene noctua, Strix aluco (Fig.

Two subspecies of the Spadefoot were distinguished earlier, but the former USSR is inhabited only one of them (Kuzmin, 1999). Recently the Spadefoot was suggested to be a superspecies. Spadefoots breed for 2-3 weeks in the second half of April to the beginning of May. 3 m) with aquatic vegetation on the bottom. Mating calls of males resemble sudden, abrupt “toc-toc-toc” or “crok-crok-crok,” which can be heard only for 30–50 m.

The Moor Frog spends the cold season buried in the soil on land. In this connection, in cold but not snowy winters it suffers from low temperatures. 4%). Feeding selectivity seems to be very low. Tadpoles eat green and diatom unicellular algae and detritus. This species is eaten by a great number of predators, such as numerous aquatic beetles, many species of fishes, birds (waterfowl), amphibians, reptiles (snakes) and mammals (mustelids). Many forms of human economic activities and, first of all, destruction and chemical pollution of breeding wetlands have a negative effect on populations of the Moor Frog.
