The African blue tit (''Cyanistes teneriffae'') is a species of bird in the Paridae family. It is found in northern Africa and the Canary Islands. Its natural habitat is temperate forests. This species and the Eurasian blue tit were formerly considered conspecific. ==Subspecies== * Ultramarine tit (''C. teneriffae ultramarinus'') Bonaparte, 1841 (La Palma, Hierro, Fuerteventura, Lanzarote, NW Africa); * Libyan blue tit (''C. teneriffae cyrenaicae'') Hartert, 1922; * Canary Islands blue tits (''C. teneriffae ssp.)'' (Tenerife, La Gomera, Gran Canaria) * *The Canary Islands group would contain five subspecies (''palmensis'', ''ombriosus'', ''degener'', ''teneriffae'', and ''hedwigae''.〔Manegold, Albrecht. (2012). On the name of the Canary Blue Tit ''Cyanistes teneriffae'' from Gran Canaria. ''Bull. B.O.C.'' 132(1): 68.〕 The Canary Islands subspecies has a black cap, and the African form has a blue back. Research is underway to split these populations into distinct species, with a peculiar "leapfrog" distribution:〔Kvist, Laura. (2006).

(HTML abstract)〕 Research published in 2007 found that African blue tits on the eastern Canary Islands of Fuerteventura and Lanzarote are indistinguishable from those in North Africa and so the subspecies ''degener'' should be regarded as a synonym of ''ultramarinus''.〔Christian Dietzen, Eduardo Garcia-del-Rey, Guillermo Delgado Castro and Michael Wink (2007).
