During the years 1991-2000,101 bird species were recorded in the city of La Plata, Argentina, 47 of which were breeding ones. The most abundant species were: Zenaida auriculata, Columba livia, Funarius rufus, Pitangus sul- phuratus, Zonotrichia capensis and Passer domesticus. Columba maculosa, C. picazuro, Fumarius rufus, Turdus rufiventris and Molothrus bonariensis have increased in number, while Passer domesticus has decreased. Zonotrichia capensis may successfully compete for food with Passer domesticus. Sturnus vulgaris and Acridotheres cristatellus are new species in the breeding avifauna of La Plata city.

PL

Na obszarze 16 km2 w latach 1991-2000 wykazano 101 gatunków ptaków, spośród których 47 gniazdowało (Tab. 1). Najliczniejszymi gatunkami lęgowymi były: Zenaida auriculata, Columba livia, Funarius rufus, Pitangus sulphuratus, Zonotrichia capensis i Passer domesticus. W okresie badań nastąpił wzrost liczebności Columba maculosa, C. picazuro, Furnarius rufus, Turdus rufiventris i Molothrus bonariensis oraz spadek liczebności Passer domesticus. Zonotrichia capensis może wygrywać konkurencję o pokarm z Passer domesticus. W drugiej połowie lat 90-tych w La Plata zaczęły gniazdować 2 gatunki egzotyczne: Sturnus vulgaris i Acridotheres cristatellus.
