Naturalized: Observation pertains to exotic population considered Naturalized: self-sustaining, breeding in the wild, persisting for many years, and not maintained through ongoing releases (may also include vagrants from established populations). Accepted by regional bird records committee(s) (e.g., Category C) and count in official eBird totals.

Provisional: Observation considered Provisional for one of two reasons 1) population is breeding in the wild, self-propagating, and has persisted for multiple years; 2) rarity record is considered likely to represent a natural vagrant but which has been treated as provisional by regional BRC given possibility of captive provenance. These species are not yet accepted by regional bird records committee(s) (e.g., Category D or E*) and count in official eBird totals.

Escapee: Observation pertains to an exotic considered Escapee (not established), often from a unique escape or release event. May include escapees that occur frequently with no indications of breeding in the wild, those with isolated or rare instances of breeding, or small exotic populations that do not yet show any indication of establishment. Escapee exotics are not counted in official eBird totals.
