Ochre-bellied Flycatcher (Mionectes oleagineus) Science Article 3 abstract The social systems and behavior of Tyrannids are best known for the North American representatives, a small percentage of a large and diverse family. In this paper, we describe the breeding season social organization and behavior of the Ochre-bellied Flycatcher, Mionecteso leagineusa, lek-breeding Neotropical Tyrannid. We describe […]

Ochre-bellied Flycatcher (Mionectes oleagineus) Science Article 1 abstract Several hypotheses suggest that the costs and benefits of display in aggregations of different sizes play a major role in both the evolution of leks and in the distribution of males across lekj of different sizes. We examined the consequences of variation in lek size for both […]
