New records of the critically endangered Ecuadorian white-fronted capuchin (Cebus aequatorialis) detected by remote cameras.

The Ecuadorian white-fronted capuchin (Cebus aequatorialis) is classified as Critically Endangered (CR) on the IUCN Red List at both international and national levels in Ecuador, and the majority of detections have been recorded from direct observation. In this work, we report the occurrence of this species in a new location in the Coastal Region of Ecuador recorded by remote cameras. Overall, eight separate detections were recorded by three unique cameras from 19 Aug to 10 Dec 2016, over seven individual days, with a detection rate of 1.4 records per 1000 camera days. One additional detection was recorded in a brief remote camera survey conducted in January and February 2018. Only two direct observations were recorded in many visits to the study area over the past several years, suggesting that the use of remote cameras could be an effective method to detect the occurrence of Ecuadorian white-fronted capuchin, particularly in tropical dry forests with low tree coverage.
