Nests that were found empty, without any sign of damage in their structure caused by predation and those with nestling aged over 21 days, were considered successful.
Thus, breeding aspects were studied in order to evaluate the role of colony sites and predation in the breeding success of red-rumped cacique in the study area.
The Wilson Bulletin 87 4: This monitoring had the objective to evaluate breeding success and also to know in which nest phase nest loss was highest.
London, Academic Press, p. Bird Conservation International 15 4: Habitat selection in temperate marsh-nesting birds.
Volume 1, Part 1 12th ed. Predation was the main factor of nests loss in the study area. Nest abandonment after eggs were laid 6. Only subscribers are able to see the bibliography.
The Auk 98 4: Lake edge colonies had mean activity duration 9. Norton and Company, p. This author considered that these females were the focus of intense aggression from adult females, which often expelled young and took over nest sites in which young females had begun to build.
MASONworking in subtropical region, found nest survival probability varying from 6. The nest fall represented 6. For each colony, the percentage of successful nests was calculated, generating the percentage of successful nests for each environment lake edge, forest and swamp.

Burst of calls from bird 15m from mic in thick forest regrowth on wetland edge. Even though in this study we did not detect a significant difference between predation rates during incubation and nestling periods, it was observed a larger nest survival probability during incubation period.

Linear regressions were used to evaluate the relationship between: Oriolus haemorrhous Avibase Haemorghous Nests abandoned before eggs were laid were not considered in the facicus success analysis. Recommended citation Fraga, R. Seven colonies were monitored, two of lake edge, two of forest, and three of swamps. Lake edge colonies presented higher predation rate, with SLAGSVOLD suggested that predation rates are frequently larger during nestling phase because nests become more exposed to visualization by predators which are conducted by adult movement for nestlings feeding.
