High Quality Content by WIKIPEDIA articles! The Rufous-naped Tit (Periparus rufonuchalis), also known as the Black-breasted Tit or Dark-grey Tit, is an Asian songbird species in the tit and chickadee family (Paridae). It was sometimes considered conspecific with the Rufous-vented Tit (P. rubidiventris), and was formerly placed in the genus Parus. This tit is a native of the western Himalayas, but has a very large range, occurring in parts of India, China, Pakistan, Turkestan, Kyrgyzstan, and Afghanistan. Widespread and common, it is not considered a threatened species by the IUCN. A songbird is a bird belonging to the suborder Passeri of the perching birds (order Passeriformes). Another name that is sometimes seen as scientific or vernacular name is Oscines. This group contains some 4000 species, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song. There is evidence to suggest that songbirds evolved about 50 million years ago in the western part of Gondwana that later became Australia, New Zealand, New Guinea and Antarctica, before spreading around the world.
