Parus is a genus of Old World birds in the tit family. It was formerly a large genus containing most of the 50 odd species in the family Paridae. The genus was split into several resurrected genera following the publication of a detailed molecular phylogenetic analysis in 2013. The genus name, Parus, is the Latin for "tit". The genus now contains the following species: \n* Great tit, Parus major \n* Japanese tit, Parus minor (split from P. major) \n* Cinereous tit, Parus cinereus (split from P. major) \n* Green-backed tit, Parus monticolus
