1. Biologia e sucesso reprodutivo de mimus saturninus (aves: mimidae) no cerrado
The Chalk-browed Mockingbird, Mimus saturninus (Mimidae) is a very common bird in cerrados, grasslands, and pasturelands with scattered trees or shrubs, also occurring in urban environments. Here I studied aspects of its breeding biology and success in a natural cerrado. Data was collected at Estação Ecológica de Águas Emendadas (ESECAE) from 2003 to 200

2. Isolamento e caracterização de locos de microssatélite para Neothraupis fasciata, (Emberizidae, Passeriformes, Aves),
Microsatellite molecular markers are small repeated sequences in tanden compound of 1 to 6 nucleotides. Widely used as genetic markers, the microsatellites have a particular attribute that is the high rates of mutation. These molecular markers or are widely used in conservation genetics, population genetics, forensic research, diagnosis of diseases, ecologic

3. Biologia reprodutiva e comportamento cooperativo em ninhos de Cyspsnagra Hirundinacea
White-rumped Tanager (Cypsnagra hirundinacea) is a cooperative breeding species, which helpers are offspring of earlier breeding seasons. This species occurs in open areas of the Cerrado (Neotropical savanna). The first chapter of this dissertation presents a description of several aspects of C. hirundinacea reproductive biology, including reproductive perio

4. Familiar neighbors enhance breeding success in birds.
We tested the hypothesis that long-term familiarity with neighbors is advantageous by determining whether male red-winged blackbirds (Agelaius phoeniceus) breeding adjacent to familiar neighbors have better reproductive success than other males. Using data gathered during a 10-yr study of breeding success, we found that males with familiar neighbors fledged,
