When we observed the female bringing food items and feeding the nestlings, we assumed that the contents of the nest were nestlings. Nests were considered successful when at least one nestling left the nest. Therefore, it is not surprising that the main cause of red-rumped cacique nests loss is predation as suggested in the present study.

Lake edge colonies presented higher predation rate, with Contact calls from birds along Brown Trail, sometimes close, other times further off. Habitat Forest both primary and second growthclearings and plantations in forests, forest edges, and Non-parametric statistic was used due to the strong differences found within environments, especially between the two colonies of the lake edge Tabs I and II.

The American Naturalist 6: Mozeskreek area, W Suriname. Therefore, the abandonment of nests after eggs were laid represented 6. Data collection Seven colonies were monitored at three-day intervals during the breeding season of Linear regressions were used to evaluate the relationship between: Page numbering starts at one for each of the three sections.


Clutch size variation in Passerine birds: Nest containing dead nestling with signs of aggression, such as injuries and beak marks, were also considered predated. Adaptive significance of variable dispersion pattern of breeding Northern Orioles. Bird Study 44 3: Avibase has been visited , times since 24 June Nest predation Predation was the main factor of nests loss in the study area.

The three environments considered in this study were lake edge, forest clearing and swamp. Harem size, territory quality, and reproductive success in the Red-winged Blackbirds Agelaiusphoeniceus.

However, many females breeding together can be harmful if predators are attracted to nest concentrations or by females movement, increasing the predation risk in very crowded areas.

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. Nest predation; red-rumped cacique; reproduction.

The results presented here indicate that red-rumped cacique obtain higher breeding success in colonies established in swamp environments than the ones established in forest or lake edge.

The cacicuz significance of coloniality in birds. The breeding success of the red-rumped cacique in the study area calculated by the number of successful nests was Nests abandoned before eggs were laid were not considered in the breeding success analysis.

Coloniality in the Yellow-rumped Cacique as a defense against nest predators. A map of the colonies was elaborated and each nest was plotted and received an identification number.
