The Cornell Lab of Ornithology builds the eBird global platform for communities and partners around the world to advance data-driven science, education, and conservation.
Eccentric-looking hornbill with a bushy, upright white crest and a white tail. Male is white from the head down to the belly; female is predominantly black, with only a white crest. Pale wing edges revealed only when in flight. Unlike many other hornbills in its range, forages primarily at lower levels in the forest, frequently descending down to the ground. Social; forages in flocks. Gives rather soothing, owl-like hooting coos.
Exotic species flags differentiate locally introduced species from native species.
Naturalized: Exotic population is self-sustaining, breeding in the wild, persisting for many years, and not maintained through ongoing releases (including vagrants from Naturalized populations). These count in official eBird totals and, where applicable, have been accepted by regional bird records committee(s).
Provisional: Either: 1) member of exotic population that is breeding in the wild, self-propagating, and has persisted for multiple years, but not yet Naturalized; 2) rarity of uncertain provenance, with natural vagrancy or captive provenance both considered plausible. When applicable, eBird generally defers to bird records committees for records formally considered to be of "uncertain provenance". Provisional species count in official eBird totals.
Escapee: Exotic species known or suspected to be escaped or released, including those that have bred but don't yet fulfill the criteria for Provisional. Escapee exotics do not count in official eBird totals.
