| Behavioral studies of birds have reported several functions for active anting. Maintenance of plumage and prevention from ectoparasites are some examples. In this context, anting by males may be of particular importance in a classical lek mating system, where male-male competition is common and individuals with higher fitness may be more successful at attracting of females. In the present note, I describe the anting behavior of White-bearded Manakin (Manacus manacus) and I relate it to lek breeding and feeding (frugivory) habits of the species. Males used up to seven Solenopsis sp. ants. They rubbed each small ant from 4 to 31 times on undertail feathers until the ants were degraded; ants were not eaten. Males then searched for a new ant in the court.... |

| Current evidence suggests that in Hetaerina damselflies males exhibit lek mating system. In this study, in order to answer if the same occurs in Hetaerina rosea Selys, we manipulated vegetation substrates used as territories and quantified the number of visiting females, males defending territories and fight intensity. We also examined whether body size and wing pigmentation are selectable traits in male-male competition, and if age affects male territorial behavior. Our results showed that males with larger pigmented areas won more contests, independently of body size. Old males changed from territoriality to sneaking strategy. Contrary to other Hetaerina species, males of H. rosea do not display lek behavior, but defend resources according to the... |

| Polythoridae comprise a widespread group of species in the New World tropics, but little is known about their behavior or life history. Here, we described the reproductive behavior of Amazonian Chalchopteryx rutilans, using mark-recapture techniques. Males were resident and territorial, though we found disputes (complex flight manoeuvres) to be rare. Trunks (rotting wood) were important to male persistence in sites, as these are the locations preferred by females for oviposition. The mating system of C. rutilans may be comparable to the resource limitation category, described by Conrad & Pritchard (1992), where males cannot control female access to oviposition sites. So, female choice becomes important and apparently, the observed displays (in... |
