Cryptic Treehunter Cichlocolaptes mazarbarnetti


Justification of Red List Category
This species was last seen in the wild in 2007 and so it could be extinct. However, given that the last sighting was relatively recent, there is a slight possibility that a tiny population remains and it is therefore listed as Critically Endangered (Possibly Extinct).

Population justification
The lack of recent sightings in areas where it has been recorded, and the fact that this species has not been found at any other sites in the region (Pereira et al. 2014) means that it if the species is extant, the global population may be suspected to be very low (<50 mature individuals).

Trend justification
With the lack of sightings it is difficult to estimate a population trend.

Distribution and population

To date, and perhaps for all time, the species has been found at only two sites in north east Brazil: Murici in Alagoas and Frei Caneca in Pernambuco. It has not been recorded since April 2007 in Murici and February 2005 in Frei Caneca (Pereira et al. 2014).


This species is found in humid forest (Mazar-Barnett and Buzzetti 2014).


This species may be threatened by the deforestation occurring within its range.
