Geographic Range [top]

Range Description:Crypterellus noctivagus is rare to locally common in the caatinga and Atlantic forests of east Brazil. The nominate race occurs from south Bahia to Rio Grande do Sul, with an apparent stronghold in south São Paulo and east Paraná (Aleixo and Galetti 1997). It is now restricted to only a few Atlantic forest sites (Cabot 1992), but appears to have always been scarce or rare in the south of its range (Hellmayr 1929, Belton 1984). The race zabele occurs from Minas Gerais (common in the north according to G. M. Kirwan in litt. 1999) to Piauí and Pernambuco (Sick 1993).

Population [top]

Population:The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).

Trend Justification:  A moderately rapid and on-going population decline is suspected, owing to rates of habitat destruction and hunting pressure.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:UnknownContinuing 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:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in caatinga and Atlantic forest, particularly remnant lowland forest from 0-300 m. It can apparently survive in degraded and secondary forest.

Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):6.8
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): It suffers from widespread and continuing habitat destruction and hunting pressure throughout its range, but can survive in degraded and secondary forest (Aleixo and Galetti 1997).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None are known.

Conservation Actions Proposed
Protect remaining habitat. Raise awareness about the species's rarity and encourage local people to reduce hunting pressure. Continue monitoring populations and assess the impacts of hunting.
