Amazing news! Last year Sean McHugh passed us information about a new population of yellow tailed woolly monkeys far to the south of their known distribution (Recently published in the journal Oryx, McHugh et al 2019). Since then, together with the Equipo Primate Loreto, We have been surveying the areas between the previously known distribution and the new sighting. Now, thanks to Elvis Charpentier Uraco, we have been able to find them, and even further south than the previous sighting. Our survey work will continue until we know the limits of their distribution in these new areas. This is really good news for the species as it means their population size may be significantly larger than thought, helping protect them against extinction.
In the photos below you can see the clear phenotypic differences between the southern population (upper) and the northern population (lower).
