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. The status of this species has not been assessed because it is noted to be common on the islands of Tenerife and Gran Canaria. The species has been used in many research studies due to its island populations and relevance to evolutionary hypotheses[2] LocationThe African Blue Tit is found in Northern Africa and the Canary Islands. It is wide spread on the Islands of Tenerife and Gran Canaria, but scare in local populations on Fuerteventura and Lanzarote[3]. DescriptionThe African Blue Tit ranges from 11 - 12 cm in size[3]. It is a small, sharp-billed, compact tit. The nominate race has a forehead and supercilium to centre of nape white, crown deep glossy blue, becoming blackish on the neck, with a blue dorsal and yellow ventral body. The song is a variable repetition of one or two notes[3]. DietThe species is known to consume a variety of caterpillars[4]. The diet is not significantly different from C. caeruleus. HabitatThe African Blue Tit prefers temperate forests, both low and high lying[3][5]. Lowlands area preferred on Fuerteventura and Lanzarote, but populations on Tenerife and Gran Canaria prefer montane forests. BreedingThe species breeds from February to July, and also possibly from October to January. It usually breeds earlier at lower levels compared to in montane areas[5]. Egg-laying occurs when the photoperiod is longer, and extra-pair mates are chosen and synchronises with the highest density of caterpillars available for prey[5][4]. This is a resident species - juveniles remain at their natal site; they do not disperse once they fledge[3]. TaxonomyThis species and the Eurasian blue tit were formerly considered conspecific. Subspecies are[2]:
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.[9] References{{commonscat|Cyanistes teneriffae}}1. ^{{cite iucn | author = BirdLife International | year = 2016 | title = Cyanistes teneriffae | journal = The IUCN Red List of Threatened Species | volume = 2016 | page = e.T103761672A104117708 | url = https://dx.doi.org/10.2305/IUCN.UK.2016-3.RLTS.T103761672A104117708.en | accessdate = 24 December 2018}} {{Taxonbar|from=Q10546857}}{{DEFAULTSORT:tit, blue, African}}2. ^1 {{Cite journal|last=Illera|first=Juan Carlos|last2=Spurgin|first2=Lewis G.|last3=Rodriguez-Exposito|first3=Eduardo|last4=Nogales|first4=Manuel|last5=Rando|first5=Juan Carlos|date=June 2016|title=What are We Learning about Speciation and Extinction from the Canary Islands?|journal=Ardeola|language=en-US|volume=63|issue=1|pages=15–33|doi=10.13157/arla.63.1.2016.rp1|issn=0570-7358}} 3. ^1 2 3 4 {{Cite web|url=https://www.hbw.com/species/african-blue-tit-cyanistes-teneriffae|title=African Blue Tit (Cyanistes teneriffae)|website=www.hbw.com|language=en|access-date=2018-10-31}} 4. ^1 {{Cite journal|last=Ziane|first=Nadia|last2=Chabi|first2=Yassine|last3=Lambrechts|first3=Marcel M.|date=December 2006|title=Breeding Performance of Blue TitsCyanistes caeruleus ultramarinusin Relation to Habitat Richness of Oak Forest Patches in North-Eastern Algeria|journal=Acta Ornithologica|language=en-US|volume=41|issue=2|pages=163–169|doi=10.3161/068.041.0201|issn=0001-6454}} 5. ^1 2 {{Cite journal|last=Ziane|first=Nadia|last2=Chabi|first2=Yassine|last3=Lambrechts|first3=Marcel M.|date=December 2006|title=Breeding Performance of Blue TitsCyanistes caeruleus ultramarinusin Relation to Habitat Richness of Oak Forest Patches in North-Eastern Algeria|journal=Acta Ornithologica|language=en-US|volume=41|issue=2|pages=163–169|doi=10.3161/068.041.0201|issn=0001-6454}} 6. ^Kvist, Laura.
