Tyto pollens is an extinct giant barn owl which lived in the Bahamas during the last Ice Age.

18,000 years ago, the sea level was 120 metres lower than today and the Bahamas existed as at least five major islands, with a land mass over 10 times the modern size.

These show that T. pollens had a diet which was largely based on the large rodent Geocapromys ingrahami, which at present only survives on a single small arid island, but which appears to have once been the only land mammal of the Bahamas and extremely common throughout most of the islands at the time.

It is thought that the changing wetter climate allowed a new habitat of Bahamian pineyards (Caribbean pine forests) to spread over the islands, which drove this main prey of T. pollens to be extirpated from all but remnant arid habitat islands, and hunting by the Lucayans may have possibly also driven the species to extinction.

[2][3] In a 1995 report Bruce G. Marcot, a forester from the Pacific Northwest Research Station in Portland, Oregon, claimed without evidence that it lived in the old-growth Bahamian pineyards of Andros Island in the Bahamas,[4] although the fossil assemblage indicates it was a species from the prairies and no fossils are known from Andros Island.
