Birdfinding.info ⇒ Known only from a single specimen collected in 1877 near Nassau by Lewis Brace, and fossil bones later recovered from cave deposits.
Brace’s Emerald †
Chlorostilbon bracei
Extinct. Formerly endemic to New Providence in the northern Bahamas.
Identification
Similar to Cuban Emerald, but slightly smaller, with a longer, more decurved bill. The male collected was mostly greenish with a golden cast on the head and back and a grayish cast on the belly. Female plumage was never documented but presumably resembled other female emeralds.
Notes
Monotypic species. For many decades, the specimen’s status as a separate species or hybrid was uncertain. Fossil bones collected on New Providence appeared to confirm that it was a member of the avifauna and therefore a full species.
