What bird sounds like a flute?

A flute-like song from shady woods is most likely a thrush. In leafy, damp forest in the East it is usually a Wood Thrush, whose song Audubon calls a series of rich, melodious, flute-like phrases. In conifer and mixed woods of the North and the West, think Hermit Thrush: one opening note, then flute-like phrases that fall away. Its cousins the Veery and Swainson's Thrush sing reedy, flute-like spirals that run down and up. Out in open grassland, a flute-like gurgle is a Western Meadowlark.

Listen: the Wood Thrush

Audubon's field guide describes the Wood Thrush's song as a series of rich, melodious, flute-like phrases, and even files it under the call type flute. The call is a sharp pit-pit-pit-pit. Audubon credits these songs with adding music to summer mornings in eastern woods, and if the flute you heard came from a leafy forest in summer, this is the first bird to check.

Wood Thrushes breed in the understory of mostly deciduous woods with tall trees, favoring damp forest and streamsides over drier woods, and they will nest in suburbs that keep enough big trees. They migrate mostly at night, many of them straight across the Gulf of Mexico, and spend the winter in the understory of lowland tropical forest. Audubon notes that numbers have declined seriously in recent decades: cowbirds lay eggs in Wood Thrush nests, broken-up forest makes those nests easier for cowbirds to find, and the tropical wintering habitat is probably shrinking.

The other flute players

Hermit Thrush: one note, then the run

Wikipedia calls the Hermit Thrush's song ethereal and flute-like: a beginning note, then several descending phrases in a minor key, repeated at different pitches. BirdNote hears long, flute-like notes backed by complex, reedy phrases. There is some arithmetic behind the beauty, too. Analysis of the song shows its notes are related by simple whole-number pitch ratios, as in much human music. The bird often sings from a high, open spot. It breeds in conifer or mixed woods across Canada, southern Alaska and the northeastern and western United States, and it is the state bird of Vermont. Most spend the winter in the southern United States and Central America.

Veery and Swainson's Thrush: the spirals

The Veery and the Swainson's Thrush are the Hermit's close relatives, and BirdNote describes the songs of all three as reedy or flute-like. What separates them is direction. A Swainson's Thrush's song spirals upward in pitch, while a Veery's phrases tend downward. Swainson's Thrushes nest in western woods and across the northern states and Canada, announce their spring arrival with soft whit calls, and usually begin full song at dusk about a week later. Many birders rank the Swainson's among the finest singers there are, with the Veery and the Hermit close behind.

Western Meadowlark: the flute in the field

Not every flute is in the woods. Audubon describes the Western Meadowlark's song as a rich, flute-like jumble of gurgling notes, usually descending the scale, and very different from the simple, plaintive whistles of the Eastern and Chihuahuan Meadowlarks. It breeds mostly in natural grassland, weedy abandoned fields and rangeland, and winters in stubble fields and other farmland. In the Midwest the Western tends to take shorter grass and drier fields than the Eastern. Its call is a throaty chook, and the birds also give a dry rattle.

How to tell which one you heard

• Where you are. Leafy, damp eastern woods with tall trees: Wood Thrush. Conifer or mixed woods in the North and West: Hermit Thrush, or a Swainson's. Open grassland, weedy fields or rangeland: Western Meadowlark.
• Which way it goes. A Veery's phrases tumble downward and a Swainson's spirals upward. A Hermit opens with a single note, falls through its phrases, then starts the next one on a new pitch.
• How it is built. A Wood Thrush sings a series of separate, rich phrases. A meadowlark's song is one quick, gurgling jumble that usually runs down the scale.
• When you heard it. Wood Thrushes are a summer-morning sound in the eastern woods. Swainson's Thrushes usually start their full song at dusk, about a week after they arrive in spring.

If the flute player stays hidden in the leaves, Warble can listen and name the bird from the song.
