In past days, while talking about Zocay Project results, someone ask me why we had so little information about Brumback nigh monekys (Aotus brumbacki) in general. In this post we are going to talk about this species, what had been done and what is still need it to be done to better understand this nocturnal primate species of Colombian Llanos.Brumback night monkeys are one of the 11 species of nocturnal monkey from genera Aotus spp. They are distributed in the piedmont of Colombian Llanos, but its eastern limits are not clearly defined, although it seems it can go up to Orinoco River. Information about this species is limited to a few studies, an undergraduate thesis from Solano in 1995 where she reported a group’s activities, home range and daily distance, as well as a list of plants from which they feed. An anecdotal report of a female Aotus brumbacki female consumed by a group of black capped capuchins (Sapajus apella fatuellus) by Carretero-Pinzón et al (2008) and a list of plants consumed by this species in forest fragments by (Vargas et al. 2023).But why there is so few studies on this species? Well, working at night have its own challenges and it is not always easy to see them and even more difficult to follow a group of this species, and other species of nocturnal animals. Another issue is that not everyone is good to work at night and to be in the dark inside a forest, this is one of those things that trigger some of our deepest fears, which make even more challenging to work with this and similar species. Some technologies can help and may be that is something we need to explore in the near future. For now, at least, we are working on two additional studies with this species that we hope can help us to better understand and protect this species in the study area and its distribution area. Studies about this species in forest fragments are important as most of its known distribution area is located in an area that is continuously deforested, so if you like to work at night and are interested in monkeys, like hot weather and don’t feel afraid of working at night inside forest, please feel free to contact me.If you want to support our activities, please visit https://fineartamerica.com/art/xyomara+carretero or get in contact with us at xcarretero@gmail.com if you want to collaborate, donate or volunteer in our activities.
