The St. Lucia Warbler (Dendroica delicata), or sucrier babad, is one of the most common birds on the island of St. Lucia, and can be found in most forest types. They can be difficult to spot, since they actively search for insects, flitting from branch to branch. Nevertheless, their beautiful plumage and charming song make the effort worthwhile. Formerly classified as conspecific with the Adelaide’s Warbler (D. adelaidae) and the Barbuda Warbler (D. subita), the St. Lucia Warbler is once again considered a species endemic to the island. Little is known about the ecology, behavior or population biology of this species.
