The St. Lucia wren is a very small passerine bird in the wren family Troglodytidae that is found on the Caribbean island of Saint Lucia. The name troglodytes means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter. It was formerly considered to be conspecific with the house wren, now renamed the northern house wren.

Typical Environment
Confined to the island of Saint Lucia, it occupies humid forests, forest edges, thickets, and overgrown plantations. It also ventures into second-growth scrub and gardens with dense shrub layers. The species favors areas with abundant understory and tangles where it can forage low and remain concealed. Nests are typically placed in cavities, crevices, or sheltered man-made sites. It adapts well to a mosaic of native woodland and disturbed habitats provided sufficient cover remains.

The St. Lucia wren is a tiny, secretive songbird found only on the island of Saint Lucia. Its genus name, Troglodytes, means 'hole dweller', reflecting its habit of slipping into crevices and cavities while foraging or nesting. Despite its small size, it delivers a loud, bubbly song and often nests in natural cavities or even man-made structures.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats with low, direct dashes
Social Behavior
Typically forms monogamous pairs that defend small territories during the breeding season. The male often initiates multiple 'dummy' nests, with the female selecting and finishing one for laying. Nests are placed in cavities or protected nooks, and pairs may reuse favored sites across years.
Migratory Pattern
Resident
Song Description
A loud, bubbly cascade of trills and rattling phrases delivered from low perches or concealed cover. Scolding call notes are dry, chattering ticks used when alarmed or agitated.
Plumage
Warm brown above with fine barring on wings and tail, and paler grayish-buff underparts. Subtle mottling on the flanks and faint streaking on the back. Texture is close and compact, with a short, often cocked tail.
Diet
Primarily consumes insects and other small invertebrates such as beetles, ants, caterpillars, and spiders. It gleans prey from bark, foliage, and leaf litter, probing crevices and tangles with its slender bill. Occasionally it may take small seeds or soft plant matter, but animal prey dominates its diet. Foraging is typically conducted low to the ground or within dense shrubs.
Preferred Environment
Feeds in dense understory, thickets, and forest edges where cover is abundant. It also forages around fallen logs, vine tangles, and stone walls near human habitation.
