Orange-crowned Warblers aren’t the most dazzling birds in their family, but they’re a useful one to learn. These grayish to olive-green birds vary in color geographically and have few bold markings. There’s rarely any sign of an orange crown, which is usually only visible when the bird is excited and raises its head feathers. They might have you scratching your head until you recognize their slim shape, sharply pointed bill, and warmer yellow under the tail. These busy birds forage low in shrubs, and are one of the few warblers that's more common in the West than the East.More ID Info
In the East, Orange-crowned Warblers are somewhat scarce, although you may find them by watching for them in late spring and late fall (primarily October) or throughout the winter in the southeastern US in low, dense habitats. Listen carefully for the high and sharp call note that the species gives frequently. In the West the species is common, often among the most abundant three warbler species on migration. On the breeding grounds listen for their rapidly trilled song. It’s similar to a Chipping Sparrow, but it descends in pitch at the end. Western birds migrate earlier than eastern birds in both spring and fall and use nearly any vegetated habitats.
Orange-crowned Warblers sometimes visit feeders for suet, peanut butter, or sugar water.
