Identify yellow canaries by their feathers, height and location. Most yellow canaries are endemic or native to the southern Africa countries of South Africa, Namibia, Botswana and Angola and thrive in the continent's karoo shrublands and savannas. They also live in the fynbos, an area at the tip of South Africa that contains shrubs and small trees.
You can also identify yellow canaries by their size and appearance. They grow up to 5 1/2 inches tall and 5 inches long and weigh less than 1 ounce. Male and female yellow canaries differ in color. Males have bright yellow bodies and heads with an olive-colored back and gray and black wing feathers. The female yellow canary is mostly gray and brown-gray with scattered olive-colored feathers on its back. Depending on its location, the colors can range from bright yellow to olive-streaked feathers.
Yellow canaries feed mostly on seeds, nectar and fruit in the plants and shrubs of its habitat, such as Eastern tree aloe, honey thorns and goose grass. It also supplements its diet with the occasional insect including termites, ants and beetle larvae. Although yellow canaries are territorial and solitary, they are monogamous, mating with the same partners for their entire lives. A clutch size generally consists of between two and five eggs, with the chicks resembling the mother at first hatching.
