C dating
.—None. For dating of other bird species at the
type
locality, see
Antigone cubensis
,
Gymnogyps varonai
and
Ornimegalonyx oteroi
, and of associated extinct mammals (
Parocnus browni
= 11,880 ± 420 to 4,960 ± 280 years
14
C BP), see
Jull
et al
. (2004)
and
Steadman
et al
. (2005)
.
Notes
.—The rarest extinct Cuban cathartid, restricted to its
type
locality. Larger and more robust than living Black Vulture
Coragyps atratus
(
Bechstein, 1793
)
and similar in size to extinct
C. occidentalis
(L.
Miller, 1909
)
, but with tarsometatarsus slender, among other characters (Suárez 2020a: 12). Also, proximal foramina of the tarsometatarsus are more distally placed in the two Cuban specimens available (S. L. Olson & WS unpubl.) than in congeneric species, but this can be variable and requires further evaluation of additional, insular fossil material. A distal fragment of carpometacarpus from a cave deposit in ASA, western
Cuba
, probably involves this taxon, but it is insufficient in diagnostic characters for a positive identification (Suárez 2020a: 13). As with Cuban Condor, the Cuban Black Vulture seems to have diverged during the Quaternary, after colonisation probably from
Florida
, evolving rapidly in isolation and depending on an endemic, insular ‘megafauna’, where competitive carnivorous mammals were absent (see
Arredondo 1976: 170
,
Morgan
et al
. 1980: 606
,

).
March (1863: 150–151)
reported vultures observed and prepared for collection by him in
Jamaica
, including the ‘John Crow Vulture [=
Cathartes aura
]’, ‘The Black, or Carrion Crow Vulture [=
Coragyps atratus
]’ and another, unknown vulture species, of which he stated: ‘In the autumn of 1828, I obtained from Great Salt Pond a specimen of a black Vulture, mottled with white spots, about the size of
Pandion carolinensis
. It was so obese, with deep fulvous fat, that I had much difficulty in preserving it in part. I sent the specimen to the Royal Dublin Society, but have received no information of its having been identified with any described species.’ The specimen, or material that matches March’s description, are unknown in the Dublin collection (P. Viscardi
in litt
. 2021). William T. March (1804–72) was a Jamaican native naturalist and collector (see
Levy 2008
,
2013
). Although the bird he collected in 1828 could have been a leucistic
Cathartes aura
(see
Zeiger
et al
. 2017
), it is also possible that it was an individual of the Cuban (Antillean?) extinct species
Coragyps seductus
, which was larger than
C
.
atratus
(Suárez 2020a). If the skin still exists, and its identity, are the subject of pending investigations.
