Weka: where and when to see them

The weka is a large, flightless rail endemic to New Zealand, recognised for its inquisitive manner and strong legs. Brown, streaked plumage provides effective camouflage in scrub despite the confidence some birds show around people. Its distribution is uneven, with regional forms and populations differing greatly in security. Introduced predators, road traffic and habitat change have caused serious declines, while local abundance in a few places can conceal the species' wider conservation challenges.

Weka forage on foot, probing litter and turning loose material with their bills. They are territorial and communicate with loud calls, often heard around dawn or dusk. Both parents care for the striped chicks, which leave the nest soon after hatching. Curious birds may investigate bags, footwear or unattended objects, but this is exploratory feeding behaviour rather than harmless entertainment when it brings them near roads, campsites or unsuitable food. Weka are strong runners and can move surprisingly quickly through dense vegetation when disturbed. Their elaborate vocalizations include cooing, whistling, and a distinctive 'wee-kaa' call, often exchanged between pairs. They are known for their bold and inquisitive nature, often approaching humans out of curiosity rather than fear.

• Weka are rails, not small kiwi.
• They cannot fly but can swim.
• Both parents help raise the chicks.
• Their exploratory behaviour can lead them to carry away small unattended objects.

Weka can be observed year-round where established populations occur. October to April generally provides longer daylight and comfortable coastal walking, but this is a visitor convenience rather than a strict wildlife season. Early morning and late afternoon often suit quiet observation. While generally active year-round, chick rearing activity in spring and summer can make them more conspicuous. On cruises, viewing opportunities from the deck are generally limited to shore excursions, as weka are largely terrestrial. Coastal walks during daylight hours offer the best chance for close observation.

Weka use forest edges, scrub, wetlands, rough grassland and coastal vegetation where ground cover and food occur together. Some inhabit modified landscapes, but safe nesting cover remains important. Their patchy distribution means apparently suitable habitat may contain no birds at all. They are particularly common on offshore islands where stoats and other introduced predators are absent. Some populations on the main islands are restricted to specific reserves or areas with intensive predator control. They are absent from significant portions of their historical range.

These adaptable omnivores eat insects, worms, slugs, fruit, seeds and small vertebrates. They also take eggs and carrion when available. Their broad diet helps them exploit changing conditions but can make introduced weka problematic on islands with vulnerable native wildlife. Their opportunistic feeding sometimes includes raiding traps set for pests, which poses a management challenge. Weka are known to cache food, especially during periods of abundance, to consume later. They can subsist on a wide variety of food items found locally, including coastal invertebrates and fish in shoreline habitats.

Identification

A robust brown body, short wings and stout pointed bill distinguish weka from the smaller, more secretive banded rail and the blue-purple pūkeko. Four subspecies are recognized, showing regional variations in size and coloration, from paler to darker brown plumages. The brown weka (G. a. australis) is found in the South Island, while the North Island weka (G. a. greyi) inhabits the North Island. The smaller buff weka (G. a. hectori) is restricted to Chatham Island, and Stewart Island weka (G. a. scotti) is found on Stewart and surrounding islands.
