Physical Characteristics
Canaries exhibit a variety of colors due to selective breeding, with the wild canary typically displaying a yellow-green plumage. Domesticated canaries, however, come in a dazzling array of colors including bright yellow, orange, white, red, and variegated patterns. They measure about 12.5 cm (5 inches) in length and weigh around 15 to 20 grams. Male canaries are renowned for their singing abilities, which they use to attract mates and establish territory, while females generally produce simpler calls.
Habitat and Distribution
In the wild, canaries inhabit semi-open areas, including woodlands, scrublands, and gardens, where they feed on a diet of seeds, fruits, and small insects. The birds are well adapted to a variety of environments, which has facilitated their spread and domestication. The natural habitats in the Canary Islands, Madeira, and the Azores offer a mild climate with abundant food resources, contributing to the species’ survival and proliferation.
Breeding and Lifespan
Canaries reach sexual maturity at around six months of age, though they typically breed from one year old. The breeding season in the wild generally coincides with the spring and summer months when food is plentiful. A female canary lays 3 to 5 eggs per clutch, which hatch after about 14 days of incubation. Both parents share in feeding the chicks, which fledge approximately three weeks after hatching. In captivity, with proper care, canaries can live up to 10-15 years, although their lifespan in the wild is generally shorter due to predation and environmental factors.
