A case of infanticide in tufted capuchin monkeys (Cebus nigritus)
Provedor de dados: Mastozoología Neotropical

According to behavioural ecology, infanticide by males would be an adaptive reproductive strategy because it allows faster fertilization of the females and reduces investment in unrelated offspring. Critics of this view indicate the lack of evidence of the behaviour for several primate species, hence the relevance of reports of observed infanticide events. Here we report a case of infant killing in a free-ranging group of tufted capuchin monkeys (Cebus nigritus).

Tool use in urban populations of capuchin monkeys Sapajus spp. (Primates: Cebidae)
Provedor de dados: Revista Brasileira de Zoologia

Capuchin monkeys, Sapajus Kerr, 1792, are known for their flexible behavior, including tool use, and their ability to survive in urban forests. We observed capuchin juveniles using wood as hammer and anvil and different materials as sponges (four tool-use events) in two geographically distinct urban populations in Brazil, in 2012: two in Goiânia, Central Brazil and two in Foz do Iguaçu, Southern Brazil. In Goiânia, a male used a detached tree branch as a hammer and a buttress root as an anvil to pound a seed of Terminalia Linnaeus. Another male used a small branch with leaves as a dipping tool to access water inside a tree trunk hole. In Foz do Iguaçu, the capuchins used a small branch and a piece of bread to obtain water by dipping them into tree trunk...
