Thamnophilidae

Post by wangrong on Tue Jan 04, 2011 12:57 pm

Thamnophilidae was removed from Formicariidae, leaving behind the antthrushes and antpittas, due to recognition of differences in the structure of the breastbone (sternum) and syrinx, and Sibley and Ahlquist's examination of DNA-DNA hybridisation.[1][2] The Thamnophilidae antbirds are members of the infraorder Tyrannides (or tracheophone suboscines), one of two infraorders in the suborder Tyranni. The Thamnophilidae are now thought to occupy a fairly basal position within the infraorder, i. e. with regard to their relatives the antthrushes and antpittas, tapaculos, gnateaters, and also the ovenbirds.[3] The sister group of the Thamnophilidae is thought to be the gnateaters. The ovenbirds, tapaculos, antthrushes and antpittas are thought to represent a different radiation of that early split.
