Tropical Shearwater

Small shearwater of the tropical Indian and Pacific Oceans, where it breeds on barren and rocky atolls and islets, venturing offshore to feed. Dark blackish brown above and white below; this combination of pattern and size distinctive within range. Similar to Sargasso Shearwater of the Atlantic, which has more extensive white on the face, and somewhat similar to larger Manx Shearwater and smaller Little Shearwater, but Tropical has mottled dark undertail coverts (white in Manx and Little).

Sightings in Sri Lanka have been recorded off the western, southern, and north-western coasts, in locations such as Hikkaduwa Beach and near Mannar Island.

The tropical shearwater (Puffinus bailloni), including those found in the waters around Sri Lanka, primarily feeds on fish, squid, and crustaceans
