The male Three-wattled Bellbird has a white head, chestnut body, and three long, obvious, blackish-grey wattles at the base of the bill. The female is much more nondescript, lacking the distinct wattles and is yellowish-green overall. Found in high mountain forests, this species is a pronounced altitudinal migrant, wintering in lowland forests. Although silent throughout most of the year, from March through June males of this species give a remarkable, far-carrying “boi-nng,” call from an exposed perch that has been the subject of many studies on vocal communication. Even though this species is known for its loud, piercing call, it is easily overlooked when silent. Only recorded feeding on fruits, the Three-wattled Bellbird may forage by aerial sally or while perched. This species has a restricted range and a small population size of less than 20,000 individuals, which is believed to be declining; due to these factors, the Three-wattled Bellbird has been listed as vulnerable on the IUCN watchlist.
