This author considered that these females were haemorrhohs focus of intense aggression from adult females, which often expelled young and took over nest sites in which young females had begun to build. Same individual as in XC Most nests were located on a position in the colony tree where we were able to access them and see their contents directly.

This test was also applied to assess if predation rate was different among the three environments lake edge, forest and swamp.

Cacicuus allows you to create and manage your own lifelists, and produce useful reports to help you plan your next birding excursion. The Auk 3: Nests were considered abandoned when eggs remained intact in the nest for haemorruous than 25 days. Anti-social and social behaviour of adolescent Yellow-rumped Caciques Icterinae: However, the difference in predation rate among the three environments was not significant, predation was the main cause of nests loss and it should be considered as an important factor supporting a higher breeding success and number of nests in the swamp environment.

It was considered as a colony a group of two or more nests established in bushes or trees, and simultaneously active during the breeding period, with movement of the individuals between nests or nest cluster.

Some females practically finished nest building and later abandoned them without laying eggs. The quality of the breeding habitat has been considered as another important factor in breeding success.

The red-rumped cacique nest survival probability was Red-rumped Cacique Cacicus haemorrhous. We found that colonies established in the swamp presented higher nest survival than the others and the ones in the lake edge had lower survival.

These authors consider that the gradient in breeding success observed is a result of differentiated vulnerability of those environments to terrestrial and arboreal predators. Many features of this site will not work without javascript. Lake edge colonies presented higher predation rate, with Therefore, the small number of nests in the lake edge colonies should be considered in the assessment of nests predation rate.
