Dentirostres

Dentirostres, a somewhat old-fashioned title for one of the subdivisions of singing Passerine birds or Oscines. The term, as equivalent to 'tooth-billed,' is used in opposition to Conirostres ('cone-billed') and Tenuirostres ('slender-billed'). It would include warblers, thrushes, chatters, crows, &c., but the character is purely adaptive to the better securing of the prey and the like, and is of little significance in classification.
