Fegis 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.

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. 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.
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.

Red-rumped Cacique (Cacicus haemorrhous)
Red-rumped cacique The red-rumped cacique Cacicus haemorrhous is a species of bird in the family Icteridae. It is a species of the Amazon Basin and the Guyanas in northern South America , and is only coastal there in the Guyanas and the Amazon River outlet to the Atlantic; a separate large disjunct range exists in all of south-eastern and coastal Brazil , including Paraguay , and parts of north-eastern Argentina. In the French zoologist Mathurin Jacques Brisson included a description of the red-rumped cacique in his Ornithologie based on a specimen collected in Cayenne in French Guiana. He used the French name Le cassique rouge and the Latin name Cassicus ruber. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition , he added species that had been previously described by Brisson.
