New Zealand Falcon

The New Zealand Falcon, known in Maori as karearea, is New Zealand's sole native falcon, found from native forest and river valleys to high-country tussock grassland. It is more robustly built and shorter-winged relative to body size than many open-country falcons, an adaptation suited to maneuvering through forest and broken terrain rather than open-sky pursuit.

Because it is uncommon and its range is naturally limited to New Zealand, any falcon feather found there in forest or high-country habitat is very likely from this species, as no other native falcon overlaps its range.

Recognizing New Zealand Falcon feathers

• Flight feathers: Dark brown above, broader-based than many open-country falcons, reflecting a more maneuverable, forest-adapted flight style.
• Tail feathers: Dark brown with narrow paler banding, moderately long.
• Body feathers: Crown and back feathers dark brown to blackish-brown; underside feathers cream to buff with heavy, bold dark streaking across the breast and flanks.
• Shaft color: Dark brown.
• Compared to similar species: As the only native falcon in New Zealand, there is little risk of confusion with other falcons; heavier streaking below and darker upperparts distinguish it from introduced or vagrant raptors that might otherwise be considered.

Adults are dark brown to blackish-brown above with cream to buffy underparts marked by heavy, bold dark streaking, and females are notably larger than males. Juveniles are similar but with even heavier, more solid streaking below, gradually thinning with maturity over successive molts.

Found across New Zealand in native forest, forest edge, river valleys, and high-country tussock grassland, from lowland areas to alpine zones. Resident, with some birds making local seasonal movements to lower elevations in winter.

Hunts birds in fast, agile pursuit through forest and open terrain, taking prey up to the size of larger native birds, and also preys on introduced species. Nests on the ground or on rock ledges, often in scrapes among tussock or under overhangs. Calls include loud, repeated 'kek-kek-kek' alarm notes. A heavily streaked dark brown feather found in New Zealand forest or high country is very likely from this species, as it is the only native falcon present.
