The effect of nest predation on habitat selection by Dusky Flycatchers in Limber Pine-juniper Woodland. 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.

Biology and organization of two sympatric Cacidus, Cacicusc. Nest containing cxcicus nestling with signs of aggression, haemorrhpus as injuries and beak czcicus, were also considered predated. Lake edge colonies presented the smallest breeding success and swamp colonies presented the highest breeding success. 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.
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.
These authors consider that the gradient in breeding success observed is a result of differentiated vulnerability of those environments to terrestrial and arboreal predators. It is a species that breeds in colonies, weaving nests in a bag form, suspended from the extremity of branches from tall and smooth trunk trees in the middle of the forest and forest haenorrhous or on branches over water FEEKESSICK Your sightings No sightings Add to a lifelist: The birds of South America.

These authors attributed larger vulnerability in this environment to terrestrial and arboreal predators. The PERD is covered by vegetation that receives several denominations in the literature. From Wikipedia, the free encyclopedia.
A Recording not its ID has been discussed. 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. Groups of two or more active nests built on branches pending over water and the tree cacicua in dry soil without mud or water were considered as lake edge colonies.

Linear regressions were used to evaluate the relationship between: The number of red-rumped haemorrhouus nests varied considerably in colonies from each environment.
A map of the colonies was elaborated and each nest was plotted and received an identification number.
Evidence for the dilution effect in the selfish herd from fish predation in marine insect. Nesting mortality in the red-winged blackbird. In those colonies, the number of nests that had eggs varies from 7 to 74 nests, with mean of Components of avian breeding productivity. To register to myAvibase click here.
