Red-eyed Vireo

Look for

A plain olive-green bird in the canopy — white underparts, gray cap with dark border, white eyebrow, and red eye (on adults; juveniles have brown eyes). Hard to see, easy to hear.

Size: ~6" — sparrow-sized.

Listen for

• Song: an endless series of short, robin-like phrases — "here-I-am... up-in-the-tree... see-me?... here-I-am..." Each phrase separated by a brief pause, sung from dawn to dusk, all summer.

A single male can sing 20,000+ phrases in one day — one of the most vocal birds in North America.

Where in Memphis

Every mature-canopy woodland. Red-eyed Vireos are abundant but hard to see — they forage high in the canopy, hidden in leaves.

• Overton Park Old Forest
• Meeman-Shelby, Wolf River, T.O. Fuller
• Shelby Farms wooded edges

Arrives late April, peaks May–July, gone by late September.

Behavior

• Canopy forager — works 40+ ft up, gleaning caterpillars from leaves.
• Sings from a perch rather than flight — but rarely stops.
• Weaves hanging cup nests in tree forks, often in young hardwood saplings.

Story

"Preacher bird"

The relentless song — pause, phrase, pause, phrase, hour after hour — earned the name "preacher bird" across the American South. Old-timers said it was like a tent-revival sermon that never ended.

Ernest Thompson Seton transcribed one male singing 22,197 songs in a single day in 1904. That record has never been approached for any other North American bird.

Cowbird victim

Red-eyed Vireos are heavily parasitized by Brown-headed Cowbirds — cowbird females lay eggs in vireo nests, and the vireo parents raise cowbird chicks. It's a major threat to their populations in fragmented forests. Memphis's large contiguous forest blocks (Old Forest, Meeman-Shelby) protect them somewhat.

Where they actually live

Red-eyed Vireos winter in the Amazon basin — the far upper Amazon of Peru, Brazil, Colombia. Every Memphis Red-eyed Vireo wintered in the rainforest. A 5,000-mile round trip for a 17-gram bird.

Fun facts

• They sing while eating — phrases are inserted between bites.
• Their "white eyebrow + dark border" pattern is the quickest ID from below.
• Nest-weaving is the responsibility of the female alone.
• Oldest known wild Red-eyed Vireo: 10+ years.
