“…Moreover, Amorim (2018) in a study carried out near the Clube Recreativo do Grangeiro, also in the APA of Chapada do Araripe, showed that the orders Araneae, Coleoptera, Hymenoptera, and Isoptera have greater relative abundance among the categories of prey available in the dry and rainy periods. In studies with lizards, birds, and snakes in Chapada do Araripe, a predominance of food from the following categories was also recorded: Isoptera, Coleoptera, and Formicidae (see Ribeiro et al, 2015; Gaiotti et al, 2017; Ferreira-Silva et al, 2019). Such findings lead us to believe that the availability of these resources in this environment may induce high consumption.…”

“…The species is strongly dimorphic, with males in definitive plumage exhibiting white body plumage and a striking red crest and mantle, whereas females and males in predefinitive plumage are green. Araripe manakins consume both fruits and arthropods, although the former are the more critical component of their diets [46]. Females lay clutches of one or two eggs during the rainy season, and nesting success is relatively high (72%) for the Neotropics [47].…”

An atypical mating system in a neotropical manakin

Most of the diversity in the mating systems of birds and other animals comes at higher taxonomic levels, such as across orders. Although divergent selective pressures should lead to animal mating systems that diverge sharply from those of close relatives, opportunities to examine the importance of such processes are scarce. We addressed this issue using the Araripe manakin ( Antilophia bokermanni ), a species endemic to a forest enclave surrounded by xeric shrublands in Brazil. Most manakins exhibit polygynous lekking mating systems that lack territoriality but exhibit strong sexual selection. In sharp contrast, we found that male Araripe manakins defended exclusive territories, and females nested within male territories. However, territoriality and offspring paternity were dissociated: males sired only 7% of nestlings from the nests within their territories and non-territorial males sired numerous nestlings. Moreover, female polyandry was widespread, with most broods exhibiting mixed paternity. Apparently, territories in this species function differently from both lekking arenas and resource-based territories of socially monogamous species. The unexpected territoriality of Araripe manakins and its dissociation from paternity is a unique evolutionary development within the manakin clade. Collectively, our findings underscore how divergences in mating systems might evolve based on selective pressures from novel environmental contexts.
