Bird communities of the southeastern Cerrado Region, Brazil

Abstract:

We investigated bird communities in Mato Grosso do Sul, central Brazil, from July 1994 to December 1996. We sampled birds with mist nets in 14 study sites, including native (cerrado, cerradão and gallery forest) and exotic (Eucalyptus) vegetation. Ninety-nine species from 21 families were represented in 1306 captures, including Antilophia galeata, endemic to cerrado region. Tyrannidae (24 species) and Emberizidae (18 species) were the most well-represented families. Cluster analyses arranged the study sites in four main groups (cerrados and cerradões, cerrados sensu stricto, Eucalyptus plantations, and "forest" habitats). Cerrados shared more species with cerradões than with gallery forests and Eucalyptus plantations. Of 41 species with six or more captures, only two were restricted to one habitat, 13 occurred in two habitats, 17 used three habitats, and 9 were found in all four habitats. Eight species were captured more often in the wet season. Thirty-four species were considered residents. Leaf-insectivores (20.2%) and omnivores (16.2%) were the most abundant guilds; insectivores dominated all four habitats and accounted for 53.5% of all captured species. Birds in Cerrado need a mosaic of habitats, and an opportunity to move among them is a crucial premise for maintaining bird populations. © The Neotropical Ornithological Society.
