Mimus gundlachii ssp. ‘Barbuda’

Barbuda Mockingbird (Mimus gundlachii ssp.)

Today, the Bahama Mockingbird (Mimus gundlachii Cabanis) is restricted to the cays off northern Cuba, the Bahamas, Jamaica, as well as Turks and Caicos, where it inhabits semiarid scrubland. However, the species is known from at least two fossil or subfossil bones found on the island of Barbuda, Antigua and Barbuda, in the Lesser Antilles. [1]

Given the fact that the birds on Jamaica are treated as a distinct subspecies, I personally assume that the birds from the Lesser Antilles most probably also represented a distinct subspecies, which disappeared probably around the Late Pleistocene/Early Holocene border but might in fact have survived for somewhat longer.

Cinclocerthia sp. ‘Barbados’

Barbados Trempler (Cinclocerthia sp.)

The next is a bird like a Thrush, of a melancholly look, her feathers never smooth, but alwayes ruffled, as if she were mewing, her head down, her shoulders up, as if her neck were broke. This bird has for three or four notes, the loudest and sweetest, that ever I heard; if she had variety, certainly no bird could go beyond her; she looks alwayes, as if she were sick or melancholly.” [1]

This account by the British author Richard Ligon from 1657 can be assigned with the utmost security to a so-called trempler (Cinclocerthia sp.), maybe a subspecies of the Grey Trempler (Cinclocerthia gutturalis(Lafresnaye)) or of the Brown Trempler (Cinclocerthia ruficauda (Gould)) both of which occur on the neighboring islands; or, given the somewhat isolated location of Barbados, may even have been an endemic species.

Whatever he case, since the island of Barbados has lost nearly all of its natural vegetation, this bird is now extinct. [2]

Toxostoma guttatum (Ridgway)

Cozumel Thrasher (Toxostoma guttatum)

The Cozumel Thrasher is, or rather was, endemic to Cozumel Island offshore the Yucatán Peninsula of Mexico.

The species reaches a length of about 21 to 24 cm.

The Cozumel Thrasher’s population was declining due to habitat destruction, when several hurricanes hit the island, leading to a further decreasing in numbers; the species was thought to have gone extinct when in 2004 it was rediscovered, only to apparently getting completely wiped out by subsequent hurricanes. It is now most likely extinct.

Allenia fusca ssp. atlantica Buden

Barbuda Scaly-breasted Trasher (Allenia fusca ssp. atlantica

The ca. 23 cm large Scaly-breasted Trasher (Allenia fusca (Statius Müller)) was described in 1776, the species is quite widely distributed over the Lesser Antilles where at least five subspecies can be distinguished.

The subspecies discussed here was endemic to the island of Barbuda, it was described as being distinct in 1993.

The biology of the Barbuda Scaly-breasted Trasher is not well known, it apparently was resticted to dry coastal shrublands and mangroves, where it fed on fruits as well as on small animals.

The Barbudan form was last recorded in 1990 and obviously was never seen again since, it is now fearded to be extinct.
