Medium-sized antshrike, with a long tail and a crest. Found in the understory and middle levels of humid forests with dense vine tangles or bamboo and in second growth areas. Usually found in pairs, but can be very hard to see. Males are all dark-gray whereas females have a cinnamon crest and bars on the rest of the body. The song is a loud and clear series of whistles “phiu phiu phiu phiu phiu.”
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.
