This is Bird Note.

In spring and summer, yellow warblers sing from tree tops in city parks and stream sides from Mexico to Canada.

These lemon yellow birds especially love willow trees near running water, perfect for building

a nest and finding food.

Males have red streaks on their breasts.

In some areas of the Caribbean and Central America, the males may also have chestnut-colored

hoods or caps.

Females are a shade paler yellow and have unstreaked breasts. The sex is split up

nesting duties. The female incubates the eggs, while the male brings food for his mate and chicks.

Though common, yellow warblers face imminent challenges. Over time, yellow warbler populations have

adapted genetically to their local climates.

That makes them vulnerable to environmental shifts, which could cause the species to lose much of its breeding range in the U.S. by 2080.

Yellow warbler chicks are at risk during spring heat waves, and wildfires can destroy trees along stream banks.

So addressing climate change means creating a more sustainable future for ourselves, but also keeping our most familiar

and beloved birds around too. For bird note, I'm Ariana Rimmel.

A special thank you to artist Heidi Stavrefsky for designing our 20th anniversary logo,

which beautifully captures two decades of Bird Note storytelling.
