Recent observations of the species in human-altered habitats such as eucalyptus plantations and young secondary forest (A. Lees in litt. 2011) suggest that it has a high tolerance of habitat degradation and disturbance. It has been suggested that the severe level of deforestation around Paragominas in the state of ParĂ¡ has probably increased the area of suitable habitat for this species. No evidence was found during three months of fieldwork in this area to suggest it is a regular target for hunters (A. Lees in litt. 2011). It is proposed that the species be downlisted to Least Concern, as it is no longer believed to approach the thresholds for Vulnerable under any of the IUCN criteria. Comments are invited on this proposal and further information on its population size is requested. Continue reading
