American Redstart vs Cape May Warbler

In short

The American Redstart and Cape May Warbler can be distinguished by their plumage and behavior. The American Redstart is known for its striking black and orange (or yellow in females and immature males) plumage and active foraging style, while the Cape May Warbler features a yellow breast streaked with black and distinctive chestnut ear patches.

Identification tips

• Plumage: Look for the American Redstart's black and orange (or yellow) plumage versus the Cape May Warbler's yellow breast with black streaks and chestnut ear patches.
• Behavior: Note the American Redstart's active tail-fanning behavior compared to the Cape May Warbler's more static foraging.
• Habitat: Consider the habitat; American Redstarts are versatile, while Cape May Warblers are linked to coniferous forests.
• Vocalization: Listen for the American Redstart's high-pitched songs, as the Cape May Warbler's vocalizations are less distinct in field guides.

Size

Both species are similar in size, typical of small warblers.

Plumage

The American Redstart has a black and orange plumage in adult males, with females and immature males showing yellow and gray. In contrast, the Cape May Warbler has a yellow breast streaked with black, a yellow rump, and chestnut ear patches. Females and immatures of the Cape May Warbler are less boldly colored.

Behaviour

The American Redstart is known for its active foraging behavior, often fanning its tail to flush insects. The Cape May Warbler is less active in this manner and is known to feed on nectar using a semitubular tongue.

Habitat

American Redstarts occupy a variety of wooded habitats, including secondary forests and urban areas. Cape May Warblers are often associated with coniferous forests, particularly during spruce budworm outbreaks.

Voice

The American Redstart is vocally conspicuous with high-pitched phrases, especially during the breeding season. Specific vocalization details for the Cape May Warbler are less documented.
