Where to Find a Canada Warbler
This bird is most visible in the late springtime. Birdwatchers who want to spot a Canada warbler have several things working in their favor. For one, this bird’s bright yellow feathers make it easy to see in its habitat. Second, male Canada warblers sing a beautiful song to attract females. In addition, these birds are known to hop around in the underbrush. So, they’re easier to see unlike other types of birds that remain high in the treetops!
In late summer, Canada warblers start their migration south through Texas, Mexico and then into South America. They arrive in South America in September or October where they stay for the winter.
One of the most interesting facts about this bird is the length of its migratory path. Its flight from South America back to its breeding ground in the northern United States or Canada adds up to 3,000 miles or more.

In the springtime, female Canada warblers build a nest by weaving together grass, twigs, leaves, and even bark. The interior of the nest is covered with animal hair or feathers, so each baby bird has a soft place to rest. Hollow logs, rotting tree stumps, and sphagnum hummocks are all appealing places for a female Canada warbler to build a nest. Of course, a female chooses an area near the ground that’s hidden by plant life. Nest construction can take a female as long as five days.
Cardellina canadensis is the scientific name of the Canada warbler. The Italian word Cardellina means goldfinch and the Latin word canadensis translates to Canada.

Canada Warbler Reproduction, Young and Molting
In April or May, male Canada warblers use their cheerful song to attract female birds. Biologists believe these birds form monogamous pairs at least for a single breeding period.
The female lays three to five white eggs with brown spots. The female sits on the eggs and is fed by the male. The eggs hatch in approximately eight to 12 days. The baby Canada warbler, also called a chick comes out of the egg with no feathers and its eyes closed. The male and female care for the baby birds.
In ten days, the chicks leave the nest, but they stay in the area for two to three weeks. During this time, they are fed and watched over by their parents until they are strong fliers and can find food on their own.
The lifespan of these warblers goes up to seven years.
