Black Harrier
Circus maurus
Genus Circus · Accipitridae
Endangered
- Habitat
- Fynbos, coastal plains and montane grassland of south-western South Africa; nests in tall ground vegetation
Key facts
- A southern African near-endemic with the most restricted range of the world's 13 harrier species, centred on the Fynbos Biome of south-western South Africa.
- One of Africa's rarest raptors: fewer than 1,000 mature individuals and under 500 breeding pairs remain, and the population is still declining.
- Its primary prey is the four-striped mouse; coastal birds take more birds, while inland Karoo populations take fewer mammals due to heat-reduced activity.
- Thought to have lost up to half of its core breeding habitat over the last century to cereal agriculture, invasive alien vegetation and urbanisation.
