|Identification information:||Medium-sized forest accipiter. Dark grey and brown above, with a slight pale supraloral and white underparts, yellow legs and a barred grey and black tail. Young have a black crown, with chestnut malar patches and broken banding on underparts. Similar spp. Very similar to Slaty-backed Forest-falcon Micrastur mirandollei, but larger, with a shorter square tail. Hints Regularly soars over forest, with a cackling kek-kek-kek-kek-kek-kek call that trails off at the end.|

|Range Description:||Accipiter poliogaster ranges over much of South America, and has recently been recorded in Costa Rica for the first time (del Hoyo et al. 1994, A. Lees in litt. 2011). In northern South America, it is rare but widespread in Colombia, south Venezuela, Guyana, Suriname and French Guiana. In north-east Ecuador it is very rare (Restall et al. 2006) . From here its range spreads southwards through Brazil, east Peru, Bolivia and Paraguay. The species's distribution reaches northern Argentina, although there have been no recent records from the north-east (del Hoyo et al. 1994).|

Trend Justification: This species is suspected to lose 16.5-21.9% of suitable habitat within its distribution over three generations (22 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to hunting and/or trapping and disturbance, and its patchy distribution and rarity (A. Lees in litt. 2011), it is suspected to decline by 25-30% over three generations.
|Current Population Trend:||Increasing|
|Habitat and Ecology:||This is a rainforest species, occurring in lowlands up to 500 m. It is also found in patches of riparian forest and other dense woodland. As a large bird it is thought to take sizeable prey, likely other birds (del Hoyo et al. 1994).|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||7.2|
|Movement patterns:||Full Migrant|
The primary threat to this species is accelerating deforestation in the Amazon Basin (Soares-Filho et al. 2006, Bird et al. 2011). Its patchy distribution also makes it susceptible to fragmentation and disturbance, and it may be hunted. However, it has been observed foraging in degraded habitat and clearly has at least some tolerance to deforestation (A. Lees in litt. 2011).
Conservation Actions Underway
Conservation Actions ProposedExpand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Conservation on private lands, through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture, is also essential (Soares-Filho et al. 2006).
