Pale-breasted Thrush (Turdus leucomelas) Science Article 1
abstract
The Grey-headed Thrush (Turdus ZezLcomelas) has a vast range in South America from Colombia eastward to the Guianas and southward to southeastern Brazil, Matto Gross0 and Peru. The representative in Surinam, T. 1. albiuenter, is confined to Colombia, Venezuela and the region from the Guianas southward to the middle Amazon and Bahia. The upper surface of thisthrush is brown, except the head which is dark greyish. The breast, abdomen and sides of the body are grey, the throat being broadly streaked with white. The axillaries and under wing coverts are bright rufous and the eyes are dark red. The sexes are indistinguishable in the field. The weights of specimens collected by me in Surinam are: 10 males, 55 to 76 grams (mean, 68), and 5 females, 67 to 75 grams (mean, 71).
