This species may have a very small population, which is threatened by deforestation. It is therefore listed as Near Threatened. If the population was found to be in decline, it might qualify for a higher threat category.
|Range Description:||Accipiter henstii is a forest raptor sparsely distributed throughout most of Madagascar but absent from the south-west (Langrand 1990). It is rare throughout its range (Langrand 1990; Morris and Hawkins 1998), but appears to be present in almost all adequately large forest blocks that have been surveyed (ZICOMA 1999).|

|Population:||The population is estimated at 1,000-3,000 individuals, roughly equivalent to 670-2,000 mature individuals.|
|Habitat and Ecology:||It occurs in primary forest, both dry deciduous and humid evergreen, and in some secondary woodlands and large Eucalyptus plantations, not always near primary forest, up to 1,800 m (del Hoyo et al. 1994). It hunts below the canopy for birds and small mammals, probably including some lemurs (Langrand 1990; Morris and Hawkins 1998). Egg-laying takes place in October-November, and the nest is large and constructed from sticks in the main fork of large trees, including those in Eucalyptus plantations (del Hoyo et al. 1994).|
|Major Threat(s):||The species is considered vulnerable to deforestation (del Hoyo et al. 1994).|
Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Conduct surveys to establish an up-to-date estimate of its population and range. Study the species's ecology. Monitor rates of deforestation across its range. Secure habitat through protected area status.
