Scientific Name: Cichlocolaptes mazarbarnetti Mazar Barnett & Buzzetti, 2014
Common Name(s):
English Cryptic Treehunter
Taxonomic Source(s): del Hoyo, J., Collar, N.J., Christie, D.A., Elliott, A., Fishpool, L.D.C., Boesman, P. and Kirwan, G.M. 2016.

Assessment Information [top]

Red List Category & Criteria: Critically Endangered (Possibly Extinct) D ver 3.1
Year Published: 2017
Date Assessed: 2016-10-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Westrip, J., Wheatley, H.
Justification:
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).
Date last seen: 2007

Geographic Range [top]

Range Description: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).
Countries occurrence:
Possibly extinct:
Brazil
Additional data:
Continuing decline in area of occupancy (AOO):Unknown
Extreme fluctuations in area of occupancy (AOO):NoEstimated extent of occurrence (EOO) - km2:
Continuing decline in extent of occurrence (EOO):UnknownExtreme fluctuations in extent of occurrence (EOO):No
Number of Locations:2Continuing decline in number of locations:Unknown
Extreme fluctuations in the number of locations:No

Population [top]

Population: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.
Current Population Trend:Unknown
Additional data:
Number of mature individuals:1-49Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:Unknown

Habitat and Ecology [top]

Habitat and Ecology:This species is found in humid forest (Mazar-Barnett and Buzzetti 2014).
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Unknown
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): This species may be threatened by the deforestation occurring within its range.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway

Conservation Actions Proposed
Conduct surveys to see whether this species is still extant. Protect its remaining habitat.

Amended [top]

Amended reason: Map edited: presence changed to Possibly Extinct. EOO removed.
