A very distinctive swallow with two long, thin feathers on its outer tail from which it gets its name. It has brilliant glossy blue upperparts and a chestnut forehead and crown that contrasts with clean white underparts. Females and juveniles have shorter tails. Found in grasslands, wetlands, open scrublands, cultivated areas and near water. Typically seen in singles, pairs, or sometimes small flocks.
Exotic species flags differentiate locally introduced species from native species.
מתאזרח: 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).
ארעי: 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.
פליט שבי: 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.
