Golden Swallow (Tachycineta euchrysea ssp. euchrysea)
The Golden Swallow is endemic to the Greater Antilles, where two subspecies are known from the islands of Hispaniola (Tachycineta euchrysea ssp. sclateri Cory) and Jamaica (nominate ssp.).
The species reaches a length of about 12 cm, its upperparts are very glossy bluish green, respectively golden green in the extinct nominate; the under parts are white.
The Golden Swallow was last seen in Jamaica in 1989, it is now thought to be extinct, the reasons for its extinction are not really well known.
***
In my humble opinion, the two subspecies might better be considered distinct species.
