Medium-sized guan with a long tail. Note the whitish eyebrow. Dark brown above and chestnut below. Favors woodlands with wet areas and gallery forests, both rich in woody lianas. Normally feeds in the canopy, but may also descend to the ground. In alarm gives a raucous barking call, similar to other guans. Less common than the similar Rusty-margined Guan; Chestnut-bellied has more prominent pale eyebrow and white-streaked back.
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.
