The white-necked thrush (Turdus albicollis) is a songbird found in forest and woodland in South America.

The crissum (the undertail coverts surrounding the cloaca) and central belly are whitish, and the chest is grey often tinged brown.

The members of the nominate group have conspicuous rufous flanks, and the bill is yellow with a dusky culmen.

The members of the phaeopygos group lack contrasting rufous or tawny flanks, and have bills that are almost entirely dusky.

The phaeopygos group (including subspecies phaopygoides, spodiolaemus and contemptus) is mainly found in the Amazon Basin, but with populations extending along the eastern slope of the Andes as far south as north-eastern Argentina, and as far north as western Venezuela, with extensions along the Coastal Range, the region centered around Serranía del Perijá and Sierra Nevada de Santa Marta, and the islands of Trinidad and Tobago.

[4] Throughout most of its range, especially in the Amazon, it is a shy species, heard far more than seen, but in Trinidad and parts of south-eastern Brazil it may be less retiring.
