extinct Giant Barn Owl from Haiti. Another good example of co-extinction. The Haitian Isobolodon Isolobon levir was the favorite prey of that owl and after the extinction of the Isobolodon it became extinct too.
(information from "The Doomsday Book of Animals").

Unfortunately there is no data at all of this species. But when you keep in mind that the size of the Puerto Rican Giant Barn Owl was between 60 cm and 80 cm I could imagine that it was similar.

After reviewing the systematics and distribution of the extinct West Indian taxa of Tytonidae (Tyto) larger than the living barn owl Tyto alba (Scopoli), we reached the following conclusions: (1) the species T. ostologa Wetmore (1922) is the only giant barn owl known so far from Hispaniola; (2) T. pollens Wetmore (1937) was a somewhat larger and even more robust representative of T. ostologa known from the Great Bahama Bank and Cuba; (3) the very rare species T. riveroi Arredondo (1972b) is here synonymized with T. pollens; (4) the smallest taxon of these giant barn owls is T. noeli Arredondo (1972a), which is widespread and abundant in Quaternary deposits of Cuba and is here reported for the first time from two cave deposits in Jamaica; (5) the only large barn owl named so far from the Lesser Antilles is T. neddi Steadman & Hilgartner (1999), which is here synonymized with T. noeli; (6) a new taxon from Cuba, T. cravesae new species, which in size approached the linear dimensions of T. ostologa, is named and described herein.

"The story runs that on February 1, 1788 M. l'Abbé Madoulé, master of mathematics, M. le Comte de Bermont, and M. Toupin climbed to the summit of La Selle from the northwest at about ten leagues from Port-au-Prince. They found trees covered with moss, the ground torn by rootings of wild pigs, and reported an abundance of pigeons, thrushes, and woodpeckers. From eight in the evening until one in the morning they heard hollow cries imitating the human voice that they attributed to some nocturnal bird, as they had seen feathers resembling those of a swan at the edge of sort of a den or cavern. The account is so definate as to suggest that they may have heard the calls of Tyto ostologa. As these adventures noted that the feathers examined were like those of a swan we may suppose that they were white, which may be a clue to the color of this bird."
