Unobtrusive and inconspicuous small flycatcher of tropical and subtropical forest; also ranges up into the highlands of West Mexico. Usually found singly, perched quietly (unless singing at dawn) and rather upright at mid-upper levels in trees; does not flick its wings and tail, unlike many small flycatchers. Can be identified by a combination of the lack of pale wingbars, a narrow whitish eyebrow, and the small, overall dark bill.
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.
