Avifauna da Escola Normal Superior - ENS/UEA e do mini campus da UFAM em Manaus, Amazonas

Abstract

Birds constitute 25% of the total number of vertebrates present in the world. With approximately 11,000 species recorded, birds play a very important role in dealing with interactions with the environment: they carry out seed dispersal, pollination, they aid in the decomposition of dead matter and serve as a biological pest controller. Because they play a key role in maintaining natural ecosystems, birds are very sensitive to anthropogenic interference. The study of the urban avifauna of Manaus can determine the status of the city's environmental quality using birds as indicators of good condition, as they respond almost simultaneously to changes in the environment. environment. Thus, bird species were recorded in two urban locations in Manaus, mini campus of UFAM and Escola Normal Superior – ENS of UEA. the visual record and a photograph of the species was carried out in the car parking area. Were made a comparison of the bird species composition of these sample areas. Were 26 species were found in UFAM and 25 species in ENS / UEA, being 19 species in common to both areas. In the total of the two areas, the most registered were: Psittacara leucophthalmus (32), Columbina passerina (32), Brotogeris versicolurus (21), Psarocolius decumanus (16), Pitangus sulphuratus (16), Tyrannus melancholicus (15), Patagioenas cayennensis (14) and Ammodramus aurifrons (14). The greatest species richness at UFAM it is probably related to the area of ​​forest present, even if secondary and with several alterations, such as deforestation and built-up areas on the university campus. In the area of ​​ENS / UEA the species observed are those common in urbanized and open environments, such as Pitangus sulphuratus, Tyrannus melancholicus, Tangara episcopus and Ammodramus auriphrons.
