Ornithocoenosis was regularly studied over a 5-hectare area in a residential district in Bratislava from 1979 to 1992, Slovakia. The quality and quantity of bird species, their relationship to the biotope, their seasonal occurrence, as well as the frequency of their occurrence, were investigated. During the past 14 years 110 bird species have been registered. 31 of them were nidificants. Species and individual variability, mainly during the nesting period, was directly dependant on climatic conditions as well as on the number of predators. A characteristic feature of the ornithocoenosis of this residential district was a relative stability of species composition. This was reflected in the high number (31) of euconstant species. The importance of the studied intravillan biotope for both nidificants and hibernants has been confirmed.
