Species

Justification
This species has a small population but there is currently no evidence that it is declining so it is consequently classified as Near Threatened. Evidence of declines may result in its uplisting to Vulnerable.

Distribution and population
Accipiter collaris is known from a few localities on the west and east slopes of the Andes from south-west Venezuela (Mérida, Táchira), through Colombia and Ecuador, with a recent range extension of 1,500 km to south Peru (Thiollay 1994). Although occasionally relatively abundant (Bierregaard et al. 1994, Thiollay 1994), it is usually rare and highly sensitive to human disturbance (Parker et al. 1996).

Population justification
The population is placed in the band 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification
There is no evidence that the population is in decline although ongoing habitat destruction may pose a threat in the future.

Ecology
It occurs in forest and forest edge, mostly subtropical and moist or wet, at 1,700-1,950 m in Peru (C. Bushell in litt. 1999) and at 600-1,800 m in Colombia (Hilty and Brown 1986, Thiollay 1994).

Threats
Forest in many parts of its range has suffered major losses, primarily due to agricultural expansion.

Conservation actions underway
None is known.

Conservation actions proposed
Study its ability to persist in degraded and fragmented habitats. Survey and attempt to estimate global population. Extend protected areas network to include further core areas of remaining habitat.
