Short summary

At the Estación Biológica Quebrada Blanco (EBQB), in north-eastern Peru, Peruvian red uakaris have been repeatedly sighted during long-term field research. The marked seasonality of sightings indicates that the EBQB area represents only a fraction of the uakari's home range and suggests that they undertake large-scale seasonal movements between different parts of the home range and between different habitats. Conservation strategies must take probably large space requirements into consideration.
