Voices & Vocabularies - Cardinals' Duet

Written by Bob Sundstrom

This is BirdNote.

[Song of Northern Cardinal male]

Rare among North American songbirds are those that sing a “duet.” A male cardinal, spiffy red with a spiky crest, perches bolt upright atop a backyard tree.

He sings a song of pure, whistled tones.

[Repeat song of Northern Cardinal male]

Now we hear a reply, precisely the same notes, but softer.

[Song of Northern Cardinal female]

He sings again [Song of Northern Cardinal male], from among a repertoire of about 10 songs. Again a soft reply. [Song of Northern Cardinal female] It’s coming from a tangle of vines below his perch.

And there she is, the author of the soft song, flying out from the vines directly to the male’s perch, alighting beside him. It’s a female cardinal, his mate, feathered in olive and muted red. Again she answers his song.

[Repeat song of Northern Cardinal female]

With most North American songbirds, it’s males alone who sing. But during the nesting season, we also hear female cardinals. Just when she sings and whether or not she matches his song may determine when the male brings food to the nest.

[Song of Northern Cardinal female]

For BirdNote, I’m Michael Stein.
