In today’s post we are going to talk about some of our recent news from the field. This month field season was a little bit longer due to a small anonymous donation to our field surveys. We continue with our samplings of Colombian squirrel monkey’s babies (Saimiri albigena) in Villavicencio and San Martin. We also had the opportunity to see other primate species during our surveys.
During these surveys we try to count as many monkey groups of black-capped capuchins (Sapajus apella), red howler monkeys (Alouatta seniculus) and ornate titi monkeys (Plecturocebus ornatus) as possible. We also have the opportunity to spend time observing Colombian squirrel monkey’s babies during their first months of their lives. At the moment, Colombian squirrel monkeys have babies from one to three months old. So, some of the older babies are starting to move a little bit away from their mother’s body, starting to bite branches and trying to bite fruits, showing interest in their environment. However, this also means that Colombian squirrel monkey’s babies living in the city, also explore human structures while growing up in the city. Unfortunately, this means that in cities babies bite not only tree branches as well as electricity cables, which is a huge risk for this endemic species of Colombian primate.
It is time for ornate titi monkey’s babies too, however the ornate titi monkey’s groups we had seen up to now didn’t have any. However, we saw one six month old black capped capuchin baby in one of the groups we saw in San Martin. No babies had been observed for red howler monkeys. We will continue surveying monkey groups in both areas and will be able to make an additional sampling in Villanueva next month. Information about when and how many babies are born every year is important information to know the birth rate of monkey’s population. Over the years we have tried to compiled information about as many groups as possible of all monkey’s species in San Martin area, however resources are not always easy to get, so in some years we had not been able to collect all the information necessary, an effort we will try to correct this year and if possible, in the following years.
