The Red Goshawk (Erythrotriorchis radiatus) is thought to be the rarest Australian bird of prey. It is usually found in the savanna woodlands of northern Australia, particularly near watercourses. It takes a wide variety of live prey, mostly birds.
The Red Goshawk was once considered to be a very large member of the goshawk subfamily. However, it is now believed that the goshawk resemblance is convergent. Experts currently group the Red Goshawk with the superficially dissimilar Black-breasted Buzzard and Square-tailed Kite as one of the Australasian old endemic raptors. It is believed that the ancestors of these birds, possibly together with a handful of species from South-east Asia and Africa, occupied Gondwana and over the millennia have diverged into their current forms.
