A medium-sized songbird endemic to New Zealand, restricted to predator-free offshore islands and North Island mainland sanctuaries. Male has a black head with conspicuous white ear tufts and a white wingbar. Note the vibrant yellow neck and shoulder band. Females and juveniles only have the white wingbar. Curious by nature, confidently approaching people at close range. Despite this, the species can be difficult to spot due to its rapid movements. Both sexes give a high-pitched, single-noted “titch” warning call. Males also produce whistled calls of 2-3 notes. Females can be distinguished from bellbirds by lack of green coloration. Also note the constantly cocked tail and the white wing patches.
