Setophaga Ruticilla Description
Black upperparts and hood, orange-red patches on wings, sides, and long fanned tail, and white underparts characterize this busy warbler. Black is the color of the bill, legs, and feet. The female has a gray head and gray-olive upper parts, as well as white underparts and yellow on the flanks and tail.
Size
These birds have a length of 4.5-5.5 in (11-14 cm) and a weight of 9 g (0.3 oz). Their wings could range from 8 in (20 cm).
Feeding
Caterpillars, moths, flies, leafhoppers and planthoppers, tiny wasps, beetles, aphids, stoneflies, and spiders make up the majority of the food. Barberry, serviceberry, and magnolia berries and seeds are the most commonly ingested berries and seeds.
Habitat
American Redstarts can be found in damp, second-growth hardwood woods with a dense shrub cover across their habitat. They are mostly restricted to forested streamsides in Washington, especially those with willow and alder thickets.
Behavior
Younger males appear less imposing (female-like) and are more submissive than their older counterparts, according to observation. Adult male American Redstarts tend to be more aggressive as they get older, which is reflected in their fierce territorial defense.
