Northern Cardinal song and call

A Northern Cardinal sounds like someone whistling loudly and clearly on purpose: a series of slurred, two-part whistles such as cheer, cheer, cheer, birdie, birdie, birdie or what-cheer, what-cheer, usually repeated several times from a high, visible perch. Both the red male and the brown female sing, and a sharp metallic chip is the everyday call you hear near feeders.

What the song sounds like

The cardinal song is built from clear, loud whistles, each one sliding up or down in pitch. A typical phrase starts with two or three long slurred notes and speeds up into a fast trill: what-cheer, what-cheer, wheet-wheet-wheet-wheet. Other common versions are the descending cheer, cheer, cheer and the rising birdie, birdie, birdie. The tone is pure and almost electronic, with none of the buzz of a sparrow or the raspy edge of a jay.

Songs last one to three seconds and are repeated many times with short pauses, so a singing cardinal is easy to track down. Males sing from the top of a shrub, a bare branch or a rooftop antenna. Unusually for a North American songbird, the female sings too, often from the nest, and pairs sometimes trade phrases back and forth.

If you are trying to whistle it yourself, aim for a loud, confident slur that drops in pitch, like a slow wolf whistle in reverse, then speed up. Cardinals will sometimes answer.

The call: a metallic chip

Away from the song, cardinals keep in touch with a short, sharp chip or tik, higher and more metallic than a sparrow's. You hear it constantly at feeders, in hedges at dusk, and as an alarm when a cat or a hawk is near. A rapid series of chips means the bird is agitated.

Fledglings beg with a thinner, buzzy version of the same note, which is why late-summer hedges seem full of squeaky cardinals.

When and where you hear it

Cardinals do not migrate, so the chip call is a year-round sound across the eastern and central United States, the Southwest and Hawaii. Singing picks up in late winter, often on the first mild days of February, when males start claiming territory, and stays loud through spring and early summer. By late summer it fades to occasional phrases, then returns with the first warm spell of the next year.

Listen at the edges: woodland borders, brushy yards, parks with dense shrubs, and desert washes in Arizona and New Mexico. Cardinals sing early, often before the sun is fully up, and again in the last hour of daylight. They are also among the last birds still calling at dusk, which is why the chip is so familiar even to people who never see the bird.

In Texas, Florida and the rest of the Southeast the cardinal is one of the most-reported birds of all, and in most eastern states it is the first card new Warble players catch.

What it looks like

The male is unmistakable: bright red all over with a tall crest, a black mask around a thick orange-red bill. The female is warm brown with red tinges on the crest, wings and tail and the same orange bill. Both are about the size of a large sparrow with a long tail. Young birds look like females but have a dark bill until their first fall.

Because cardinals stay all year and come to sunflower seed, they are often the first bird people learn by sight. Learning the song is the next step, and it is an easy one.

Birds that sound similar

• 
  Tufted Titmouse

  The titmouse's peter, peter, peter is also a loud clear whistle, but it stays on two notes and never speeds into a trill. Cardinals slur and accelerate.

• 
  Carolina Wren

  A Carolina Wren's teakettle, teakettle is louder for its size and rolls in three-syllable bursts. It is more rhythmic and less whistled than a cardinal.

• ?
  Pyrrhuloxia

  The desert cardinal of Texas and Arizona sings a thinner, shorter version of the same whistles. Where both live, look for the gray body and yellow parrot-like bill.

Where the Northern Cardinal card lives

In Warble the same bird can be an easy card in one state and a prized one in another, because each album ranks its birds by how often people really report them there. The Northern Cardinal appears in 39 state albums:
