A compact raptor endemic to New Zealand, with streaky cream-and-brown breast and reddish-brown undertail. In flight, note rapid beating of long pointed wings, and long rounded tail shape while gliding. Females are much larger than males. Widely distributed throughout New Zealand in native and exotic forest, as well as in tussock grassland and farmland. Will aggressively dive-bomb intruders close to nesting sites. Distinctive “kek-kek-kek” call given during attacks. Similar to Swamp Harrier but smaller; rarely feeds on road kill, actively chases prey, and glides with wings set flat rather than a shallow “V” shape like the Swamp Harrier.
