Cyanistes is a genus of birds in the tit family Paridae. The genus was at one time considered as a subgenus of Parus.In 2005 an article describing a molecular phylogenetic study that had examined mitochondrial DNA sequences from members of the tit family, proposed that a number of subgenera including Cyanistes be elevated to genus status.

The word tit is today used for a number of small birds, especially of the family Paridae. Originally, it was used for any small animal or object. [14] Five subspecies are recognised. [8]
The leg of passerine birds contains an additional special adaptation for perching.

This enables ...
