The bare-necked umbrellabird (Cephalopterus glabricollis) is a species of

Cotingidae. It is found in the Talamancan montane forests of Costa Rica and Panama
. Bare-necked umbrellabirds live only in forests and their diet consists mainly of fruits.

Taxonomy and systematics

specific epithet glabricollis is from the Latin glaber, meaning bald, and collis, meaning necked.[4]
It is monotypic.

Description

The bare-necked umbrellabird is a large, bulky, and crow-like bird, being the largest passerine in its range. It is also among the largest of the cotingas, with only the Amazonian umbrellabird being larger. The males are larger than the females, being 41 cm (16 in) in length and weighing 450 g (16 oz), compared to the females' 36 cm (14 in) and 320 g (11 oz).[5]

Distribution and habitat

The bare-necked umbrellabird is found in

primary forest throughout its range, although some birds have been seen foraging in secondary forest. It can also be found in areas with dense understory and near fruiting trees.[7] The species follows an annual altitudinal migration based on fruit availability, with most of the year being spent in lowlands between elevations of 100–500 m (330–1,640 ft) for males and at 200 m (660 ft) for females. During the breeding season between March–June, umbrellabird populations move higher up to elevations of 1,000–1,500 m (3,300–4,900 ft), coinciding with the highest fruit availability in these areas.[8]

Behavior and ecology

Diet

The bare-necked umbrellabird is mainly frugivorous, feeding on Marcgraviaceae, Urticaceae, Arecaceae, Lauraceae and Annonaceae berries, along with other fruits. It has also been known to feed on lizards, frogs, insects and larvae. Fruits are plucked from vegetation in flight or gleaned with heavy hops. A juvenile was also observed eating arthropods that were flushed out by a swarm of army ants in Costa Rica.[9]

Breeding

Breeding occurs between March and June in Costa Rica and between April and September in Panama. Like other cotingas, male bare-necked umbrellabirds perform leks to attract females.[10]

Status

It is listed as endangered on the IUCN Red List. Its global population is estimated to be less than 2,500 mature individuals and decreasing.[11]
