AMPHIBIANS, REPTILES, MAMMALS
The rich hydrological net is very convenient for amphibians. In the Park 11 species of amphibians, bound to small or big extent with water environment, have been recorded. Their mating season first begins the Ranaidae family: Common Frog (Rana temporaria), Moor Frog (Rana arvalis) and also Common Toad (Bufo bufo). During this season Moor Frog males turn blue.
Only three species of reptiles dwell in the Park: Grass Snake (Natrix natrix), Anguis (Anguis fragilis) and Sand Lizard (Lacerta agilis). Grass Snake, as an animal that lives mainly in water environment, is quite numerous and the remaining two species are recorded rarely.
Warta Mouth National Park’ mammals record includes 39 species. Among them 6 belong to insectivores order (Insectivora), 2 species belong to the choroptera (Chiroptera) order (this order requires further research in this area), 1 species from lagomorpha (Lagomorpha) order, 14 species of rodents (Rodentia), 11 species from the carnivore (Carnivora) order and 5 species from the artiodactyls (Artiodactyls) order.
