ABSTRACT
Extra group copulations are rarely observed among the Alouatta genus, which lives in a fragmented area in Brazil. Here, we describe the second extra group copulation in A. caraya in literature, which was the first from Brazil. This happened in the southeast urban island forest, which measures 25 ha. In this forest there are two troops one of them with thirteen howlers and the other with four. These howlers may be extinct in a few years since in the region there is only 3.89 % of native forests and high anthropic action due to agribusiness. We discuss the possible issues that led to the extra group copulation.
RESUMO
Cópulas extra grupo raramente são observados em animais do gênero Alouatta, que vivem em áreas fragmentadas do Brasil. Aqui, descrevemos a segunda cópula extra grupo em A. caraya na literatura, que foi a primeira do Brasil. Isso aconteceu na floresta ilha urbana sudeste, que mede 25 ha. Nesta floresta existem dois bandos um deles com treze bugios e o outro com quatro. Estes bugios podem ser extintos em poucos anos, uma vez que na região há apenas 3,89% de florestas nativas e alta ação antrópica, devido ao agronegócio. Nós discutimos os possíveis aspectos que levaram à cópula extra grupo.
