As its name implies, this species was endemic to the Bermuda Islands; it is known from subfossil remains and apparently from a contemporaneous account made by captain Diego Ramírez who spend some time ashore for repairing his ship(s) in 1603 and which mentions handsome sparrowhawks that are so stupid that they could easily be clubbed to death. [1]

The species must have disappeared very shortly after that date, since no other traveler subsequently mentions any hawks from the Bermuda Islands.
