Atlantic canary

life science Maturity 5-7 Next article →

The Atlantic canary, known scientifically as Serinus canaria, is a small passerine bird. It belongs to the genus Serinus within the Fringillidae family, which is the true finch family. This bird is often called the wild canary or the island canary. It serves as a natural symbol of the Canary Islands, alongside the Canary Island date palm. While the wild birds are usually yellow-green, they are famous for being the ancestors of domestic canaries.

Understanding the appearance of the Atlantic canary requires looking at the differences between genders and ages. Adult males feature a yellow-green head and underparts. They often have a yellower forehead, face, and supercilium, which is a stripe above the eye. Their lower bellies and undertail-coverts are whitish with dark streaks on the sides. The upperparts are grey-green with dark streaks, and the rump is a dull yellow. Females look similar but are much duller, with greyer heads and less yellow on their underparts. Juvenile birds are mostly brown with dark streaks.

The history of how we name and classify this bird is quite long. In 1555, the Swiss naturalist Conrad Gessner used the Latin name Canaria in his book Historia animalium. Later, in 1758, the Swedish naturalist Carl Linnaeus formally described the species in his work, Systema Naturae. He originally placed the bird in the genus Fringilla and named it Fringilla canaria. In 1816, the German naturalist Carl Ludwig Koch introduced the genus Serinus. Today, the Atlantic canary is considered monotypic, meaning there are no recognized subspecies. It is closely related to the European serin, and the two can produce fertile hybrids about 25% of the time.

The bird's name is tied to the Canary Islands, which has a complex history. One theory suggests the name comes from the Latin "canariae insulae," meaning islands of dogs. This refers to large dogs kept by the people living there. Another legend says the islands were named after a fierce tribe called the Canarii. The famous "canary yellow" color seen in pets actually comes from a mutation. This mutation suppressed the melanins, which are the pigments that create the original dull greenish color of the wild bird.

These birds are endemic to the Macaronesia region in the eastern Atlantic Ocean. This includes the Canary Islands, the Azores, and Madeira. In the Canary Islands, populations are estimated at 80,000 to 90,000 pairs. The Azores host between 30,000 and 60,000 pairs, while Madeira has 4,000 to 5,000 pairs. They live in many habitats, such as pine forests, laurel forests, and sand dunes. They are often found in semi-open areas with small trees, like orchards or gardens. They can live at various elevations, reaching above 1,500 meters in the Canary Islands.

Reproduction for the Atlantic canary involves specific nesting and breeding behaviors. They are gregarious birds, which means they are social and often nest in groups. Each pair defends a small territory. They build cup-shaped nests from twigs, grass, and moss, lining them with hair and feathers. The eggs are pale blue or blue-green with violet or reddish markings on the broad end.

A typical clutch contains 3 to 4 eggs, though sometimes there are 5. The eggs are incubated for 13 to 14 days. The young birds usually leave the nest between 14 and 21 days after hatching.

Biological processes during development can sometimes be difficult for the birds. The species experiences inbreeding depression, which can be more severe during early development. This is often linked to hatching asynchrony, where eggs hatch at different times. This creates differences in the age and size of the chicks. The first hatched chick lives in a more benign environment compared to the last hatched chick.

This competition for resources is a natural part of their life cycle.

Beyond their natural home, humans have moved these birds to many other places. They were introduced to the Midway Atoll in 1911 and became established there. They were also brought to Bermuda in 1930. However, the Bermuda population declined in the 1940s because scale insects destroyed the Bermuda cedar trees. By the 1960s, the birds had died out in Bermuda. They are also found on Ascension Island and are known to occur in Puerto Rico, though they are not yet established there.
