During the Northern Hemisphere’s coldest days of the year, migratory birds that fly south for the winter warm their wings in the copious sunshine near the Equator. BirdNote’s Michael Stein tracks down these savvy sun-seekers.

Transcript

CURWOOD: Migratory birds that fly south for the winter are now warming their wings in the ample sunshine near the Equator. It’s hard not to envy them during the Northern Hemisphere’s coldest days of the year. So let’s live vicariously for a moment, and take a trip to Central and South America with BirdNote’s Michael Stein, as he follows these savvy sun-seekers.

STEIN: Where have the birds of summer gone? In July, you might have heard this dawn song – many birds singing at first light. [Full dawn chorus] Today, in winter, how utterly different the morning sounds.

[A few calls of Black-capped Chickadee.]

Where are the summer singers now?

[Song of the Swainson’s Thrush]

There’s the flutelike song of a Swainson’s Thrush, a bird now wintering in Central and South America, maybe as far south as Bolivia.

Catch the rhythmic notes of a Warbling Vireo [song of Warbling Vireo] interspersed with lilting phrases of a Black-headed Grosbeak [song of Black-headed Grosbeak]

Warbling Vireos are now spread through much of Central America while Black-headed Grosbeaks have migrated to Mexico.

[Orange-crowned Warbler]

There’s the descending trill of an Orange-crowned Warbler, against a backdrop of robins. The warbler makes Mexico its winter home, as do some of the robins.

Now the raspy “fitz-bew” song of a Willow Flycatcher.

[song of Willow Flycatcher]

January finds it tucked away in Costa Rica or Panama. As winter turns to spring, these memorable singers will begin to fly north, where they will once again grace us with their rich dawn chorus.

I’m Michael Stein.
