Avifauna in a section of the urban area of Uberlândia, MG
Abstract
Birds are intensely researched in urban areas. In this study, richness, composition and frequency of contact of bird species were registered in a section of the urban area of Uberlândia, state of Minas Gerais. The avifauna was sampled between October 2003 and August 2004. Observation points were disposed in three avenues of the city and the observations were made in the morning in sessions of eight minutes each. The species were registered by visual and/or acoustic contacts. We sampled 1,080 contact points, totaling 144 hours of observation. A total of 66 species were registered (10 orders, 29 families and 59 genders). The Passeriformes were the most representative order, particularly the families Emberizidae and Tyrannidae. Among the Non-Passeriformes orders, Apodiformes and Columbiformes were most apparent. In the rainy season, 61 species were registered against 52 in the dry season. Resident species and probable residents represented nearly 80% of the registered birds. We made 9,417 contacts, 3,812 in the wet season and 5,605 in the dry season. Insectivors and omnivors were the dominant species. The richness and composition of the avifauna were clearly representative in relation to current knowledge about the avifauna in Uberlândia.
