Description

South Padre Island - Texas

Swainson's warblers are a small and rather undistinguished songbird, though are fairly large for a New World warbler. Adults grow to 12.5–16 cm (4.9–6.3 in) in length and 11–20.5 g (0.39–0.72 oz) in weight. The wingspan averages 23 cm (9.1 in).[3][4] They are a plain olive-brown above and pale yellow-white below. They have a whitish eyebrow stripe that runs above their eye, and the top of their head is a rusty brown. Unlike most other New World warblers that are mostly dimorphic, there is no difference in appearance between a male or female Swainson's warbler.

Distribution and habitat

Swainson's warblers are uncommon, mostly found in flooded swamplands and canebrakes of the south-eastern United States. More rarely, they will also occur in rhododendron thickets in the southern Appalachian Mountains. They are a migratory species, with part of the population migrating southeastwards to the Greater Antilles (where it overwinters in the Blue Mountains of Jamaica for example[5]) and the other southwestwards to the Yucatán Peninsula region in winter.

Behavior

Breeding

This species begins breeding at about 10 months of age.

nesting season. These birds live to as old as eight years.[6]

Taxonomy

No

subpopulations conform to the different wintering areas.[7]

In some migrant birds, it is known that the initial direction of the migration is set by fairly simple

bird banding data is needed to determine whether this mechanism applies in Swainson's warbler.[7]
