Brown Trembler

The Brown Trembler (Cinclocerthia ruficauda), known locally in Dominica as the Soucouyé, is a standout species in the island’s rich tapestry of wildlife and tropical forest life. Endemic to parts of the Lesser Antilles and notably abundant in Dominica’s mountain villages and nature reserves, this bird is a cherished sight among those passionate about nature walks and birdwatching on the island.

Description and Behavior

Measuring 23 to 26 cm (9–10 inches), the Brown Trembler features a plump rufous-brown body, grayish head, slightly curved black beak, and bright yellow eyes. It is named for its peculiar display—when excited or alarmed, the bird trembles its wings and entire body, creating a fluttery motion unique among Caribbean species. Both sexes share similar plumage, but females tend to have slightly longer beaks.

Habitat and Range

In Dominica, the Brown Trembler thrives in humid evergreen forests, secondary growth, and plantation edges, from sea level to elevations nearing 1,200 meters. It is commonly seen foraging in dense vegetation, including along the Syndicate Nature Trail, where birders and eco-tourists often hope to spot it. This adaptable species occupies both remote jungle interiors and more accessible forest corridors near villages and agricultural lands.

Diet and Vocalizations

Its diet consists of fruits, insects, small invertebrates, and occasionally small vertebrates. The bird forages by probing leaf clusters, vine tangles, and epiphyte-covered branches, usually in the understory or mid-canopy layers. Its vocalizations include warbled phrases and a nasal “yeeeah” call, often repeated in sequences—making it easier to detect even when camouflaged in foliage.

Conservation and Eco-Tourism Value

Classified by the IUCN as a species of Least Concern, the Brown Trembler remains relatively secure in Dominica, thanks in part to the island’s dedication to forest conservation and biodiversity protection. However, habitat loss from deforestation remains a concern. As interest in eco-tourism and birdwatching grows, efforts to protect habitats like those along the Syndicate Nature Trail contribute directly to its long-term survival.

Whether encountered on a forest walk or during a birding expedition, the Soucouyé offers visitors a fascinating glimpse into the biodiversity that makes Dominica the true Nature Island of the Caribbean.
