The studies were accomplished during the spring-winter period of 2012 in various types of ecosystems from Chisinau city and its surroundings. The mammal fauna of the city is rather rich, being registered 39 mammal species: 6 insectivore species, 9 bat species, 16 rodent species, 1 lagomorph species, 5 carnivorous species and 2 artiodactyl species. 117 bird species were registered on the territory of the city during all phenological periods. The domination degree of bird species decreases from cold period toward summer, reaching its minimum in nesting period, when bird distribution is more uniform. In post-breeding period and during autumn migration the dominance degree increases again, fact connected to the accumulation of some species in locks and their uneven distribution. Among reptiles 4 species were registered and among amphibians 9 species.
