St. Kitts Bullfinch (Pyrrhulagra grandis)

The St. Kitts Bullfinch was described in 1882, originally as a subspecies of the Puerto Rican Bullfinch (Pyrrhulagra portoricensis (Daudin)) (see photo).

… a short description: 

Similar to P. portoricensis but much larger and with the rufous markings darker (intermediate between ferruginous and vinaceous-rufous); that of the throat more restricted, scarcely extending to the chest, and that of the under tail-coverts mixed with black.” [1]

The species was endemic to the island of St. Kitts, where it was restricted to the higher slopes of Mt. Misery, the highest part of the island, it may very likely once have been found all over the island and very likely also on the neighboring islands of Nevis and St. Eustatius, which were connected with St. Kitts during the last glacial period.

The St. Kitts Bullfinch was originally known from nine specimens all of which had been collected in 1880 by Frederick A. Ober, an American naturalist, and the species was considered extinct since that date, however, a specimen that previously had been overlooked, was found in the collection of the National Museum of Natural History of the Smithsonian Institution in Washington, D.C., USA; this specimen was collected in 1929 or 1937.
