Yellow warblers are widely distributed, nesting from the Arctic Circle to Mexico.

A flash of yellow among the green—if you've spotted it, you've probably seen a yellow warbler. These tiny songbirds, like many others, bring a pop of colour to the Canadian landscape every spring, sticking around through summer. Hopping from branch to branch, they spend their day feasting on insects like caterpillars and beetles.

They thrive in wetlands, woodlands and gardens, making their homes in shrubs and small trees During the breeding season, males turn into tireless singers, hoping to win a mate with their sweet tunes. When it's time to nest, females carefully weave small cup-shaped homes from grass, plant fibres and feathers, ensuring a cosy spot for their eggs. But here's something impressive—yellow warblers won't tolerate freeloaders. If a brown-headed cowbird sneaks an egg into their nest, these clever birds simply build a new layer over it, protecting their own offspring. As summer ends, they embark on a journey south to Central and South America, spending the colder months basking in warmer climates before returning.
