The grey-backed hawk has a varied diet, mainly feeding upon reptiles during the breeding season, but also taking rodents, small birds, amphibians, crabs, earthworms and large insects (2) (5). On average, the grey-backed hawk will tackle prey at least as long as its own body, though it has been observed, on occasion, to take prey almost twice its length (5).
Studies suggest that the grey-backed hawk breeds almost all year round, but most frequently during the rainy season, from January to June. A large nest of up to 79 centimetres in diameter is constructed in the upper canopy of tall trees, in which the female lays a single bluish-white egg. Following the 36-day incubation period, the chick remains in the nest for a further 72 days, by which time it is ready to leave (5).
