Bird diversity in an urban ecosystem: the role of local habitats in understanding the effects of urbanization Iheringia, Sér. Zool.
Rodrigues,Aline Goulart; Borges-Martins,Márcio; Zilio,Felipe.
ABSTRACT: Urbanization causes environment changes that directly affect biotic diversity, and understanding the relationship between fauna and urban features is a key aspect of urban planning. Birds are particularly affected by urbanization. Noise levels, for instance, negatively affect birds’ behavior and social communication, while the presence of green areas promotes bird diversity. The effects of urbanization could differ according with the level of urbanization, and our goal was to understand how bird species assemblages are related to urban features in an intermediate stage of urbanization (a city in Brazil with 2,470 inhabitants/km²). We used canonical correspondence analysis (CCA) and generalized linear models (GLM) analyses to assess how bird...

Breeding biology and conservation of hawk-eagles (Spizaetus spp.) (Aves, Accipitridae) in southern Atlantic Forest, Brazil Iheringia, Sér. Zool.
Zilio,Felipe.
ABSTRACT Neotropical hawk-eagles (Spizaetus spp.) are large forest raptors, having low population densities and high sensitivity to human disturbance. The three species of Brazil’s Atlantic forest (S. ornatus, S. melanoleucus, S. tyrannus) are threatened and little is known of many aspects of their biology, such habitat requirements, nesting behavior, and food habitats. Here I present data about the breeding biology, diet and behavior of the Ornate Hawk-Eagle (S. ornatus; OHE) and the Black-and-white Hawk-Eagle (S. melanoleucus; BWHW), and estimations of distribution - extent of occurrence (EOO) - and population sizes for the three hawk-eagles of the southern Atlantic Forest. I compiled data from nine years of field studies done in Rio Grande do Sul and...

First record of breeding of the Ornate Hawk-Eagle (Spizaetus ornatus) in Southern Brazil Hornero
Joenck,Cristian M; Zilio,Felipe; de Mendonça-Lima,André.
We provide the first record of breeding of the Ornate Hawk-Eagle (Spizaetus ornatus) for southern Brazil. In September 2005 a nest was found inside the reservoir of the Barra Grande Hydroelectric Power Station, northern Rio Grande do Sul. On the nest there was a nestling around two months old. Based in prey remains collected on the nest, birds were the main item in diet. This is an endangered species in the Atlantic Rain Forest biome in Brazil and the presence of the nest and nestling offer evidence of reproduction in Southern Brazil.
