Puerto Rico Bushfinch (Pedinorhis stirpsarcana)

The Puerto Rico Bushfinch was a large finch-like bird with a long and narrow beak that is known from (sub)fossil remains that were found in cave deposits on the island of Puerto Rico and that could be dated to Late Pleistocene age, however, it is believed that some remains from other fossil sites are younger.

The remains were found in association with the fossils of species that are typical for open, arid environments and it is thought that the species disappeared due to postglacial reduction of these arid habitats. [1]
