Patterns of nest usurpation: when should species converge on nest niches?

Article Abstract:

Nest usurpation and nest-niche convergence have higher prevalence in valuable nest areas, like cavities and enclosed nest areas. They are also common in areas with low structural heterogeneity of vegetation and diverse assemblages of possible competitors/associates and predators. Species that excavate or form cavities and enclosed-type nests are usually hosts of the usurpers. Cavity usurpations are common in temperate zones, while enclosed nest usurpations are common in closed habitats and tropical/subtropical zones.

Variation in foraging behavior among nesting stages of female Red-face Warblers

Article Abstract:

The foraging behavior of breeding female Red-faced Warblers, a ground-nesting, insectivorous passerine in which the female incubates without the presence of the male, was studied during the egg-laying, incubation and nestling stages. Findings showed that all factors varied among nesting stages, with prey attack frequency and search speed substantially increasing from egg-laying to incubation through the nestling stage.

Relationship between tail color pattern and reproductive success, mate acquisition and nest predation in Rufous Bush Chats

Article Abstract:

Research is presented concerning the importance of tail color pattern in the Rufous Bush Chat. The effect of bright colors on the successful acquisition of mates, breeding success and the reduction of nest predation is discussed.
