The African blue tit (Cyanistes teneriffae) is a species of bird in the family Paridae. It is found in northern Africa, Pantelleria (Italy) and the Canary Islands (Spain). 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]

Contents

Location

The African blue tit is found in Northern Africa, Pantelleria and the Canary Islands. It is widespread on the Islands of Tenerife and Gran Canaria, but scarce in local populations on Fuerteventura and Lanzarote. [3]

Description

The African blue tit ranges from 11–12 cm (4.3–4.7 in) 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]

Diet

The species is known to consume a variety of caterpillars. [4] The diet is not significantly different from the Eurasian blue tit .

Habitat

The African blue tit prefers temperate forests, both low and high lying. [3] [4] Lowlands area preferred on Fuerteventura and Lanzarote, but populations on Tenerife and Gran Canaria prefer montane forests.

Breeding

The 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. [4] 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. [4] This is a resident species—juveniles remain at their natal site; they do not disperse once they fledge. [3]

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. [8]

Covering 845.92 square kilometres, Lanzarote is the fourth-largest of the islands in the archipelago. With 158,798 inhabitants at the start of 2023, it is the third most populous Canary Island, after Tenerife and Gran Canaria. Located in the centre-west of the island is Timanfaya National Park, one of its main attractions. The island was declared a biosphere reserve by UNESCO in 1993. The island's capital is Arrecife, which lies on the eastern coastline. It is the smaller main island of the Province of Las Palmas.

<i>Gallotia</i> Genus of lizards

The genus Gallotia are the lacertids of the Canary Islands. This genus consists of a group that has been evolving there ever since the first islands emerged from the sea over 20 million years ago. The endemic species and subspecies of this group have a number of characteristics that make them quite special within their family (Lacertidae); their only close relatives are the sandrunner lizards (Psammodromus) of the western Mediterranean region. Gallotia are characteristic for eating significant quantities of plants, and several lineages are often presented as classic examples for insular gigantism. However, a find of an even larger Gallotia species from the early Miocene of mainland Europe casts doubt on this assumption. Instead the ancestor of all modern Gallotia species of the Canary islands was probably already very large but carnivorous.

<i>Canariomys</i> Extinct genus of rodents

Canariomys is an extinct genus of rodents that once existed on the islands of Tenerife and Gran Canaria, part of the Canary Islands, Spain. These giant rats could reach a weight of about 1 kg (2.2 lb). They were herbivores; their diet was based on plant materials, probably soft vegetables such as roots, ferns, and berries, but not grass. C. tamarani were considered herbivores, eating everything plant-like except grass with good digging skills. While C. bravoi were considered as a rat character, because of its large size, with an omnivorous diet with good climbing skills. They were one of two groups of rodents native to the archipelago, alongside the lava mouse, which was native to Fuerteventura and Lanzarote.

Tourism is an essential part of the economy of the Canary Islands, a Spanish archipelago located in the Atlantic Ocean, 100 kilometres west of Morocco.

Tourists seeking sunshine and beaches first began to visit the Canaries in large numbers in the 1960s. The Canary Islands are a leading European tourist destination with very attractive natural and cultural resources.

As in the rest of Spain, the majority religion in the Canary Islands is the Catholic Church. The Catholic religion has been the majority since the Conquest of the Canary Islands in the fifteenth century. This religion would largely replace the Canarian aboriginal religion through the prohibition of the latter and syncretism. According to a survey conducted in 2019, Canary Islands is the fifth autonomous community in Spain with the highest percentage of people who declare themselves to be Catholics after the Region of Murcia, Extremadura, Galicia, Aragon, and Castile and León. 76.7% of the population is Catholic.
