Revision as of 01:04, 1 September 2009
Alternative names: Bare-eyed Robin; Bare-eyed Thrush; Spectacled Thrush
Includes: Ecuadorian Thrush
- Turdus nudigenis
Identification
Upperparts are plain brown, with underside lighter. Throat is striped with white and brown, but a much more obvious field mark is the large yellow eyering that consists of bare facial skin. The bill is yellow. The color of the brown parts can vary quite a bit, some of the variation might be dependent on light quality, but some may also depend on geographic variation.
Similar Species
The yellow eyering is shared with Forest Thrush, but the latter species has underside scaled in brown and white.
Naming
This species has in the Americas traditionally been known as Bare-eyed Robin or Bare-eyed Thrush, and those are the names mostly used in local field guides. However, Bare-eyed Thrush on a world wide basis refer to the African species Turdus tephronotus. Therefore, the South American Classification Committee and IOC have changed to Spectacled Thrush, which seems to be the name of the future for this species (Yellow-eyed Thrush is a misnomer as the eye is not yellow).
Distribution
Western Ecuador, North-western Peru, Northern Brazil to Colombia, Trinidad and Tobago, and the Lesser Antilles reaching at least to Guadeloupe. This bird has been spreading north through the Lesser Antilles for example arriving in Martinique in 1951.
Taxonomy
Three subspecies:
- T. n. nudigens in the Lesser Antilles, Trinidad and Tobago, and northern South America to the Amazon river from Colombia to the Guianas
- T. n. extimus in Brazil south of the Amazon
- T. n. maculirostris in Ecuador and Peru
Maculirostris has sometimes been split as Ecuadorian Thrush, and a recent decision by SACC indicates that this is the trend again.
Habitat
It seems mainly to occur in cultivated areas and open dry forest in Dominica, while the Forest Thrush is found in old growth rainforest.
Behaviour
This thrush is agressive towards other similar birds and has been suspected as a culprit in the near extinction of Forest Thrush from St. Lucia.
