Nest, Eggs, and Nesting Behavior of the Gray Trembler (Cinclocerthia gutturalis) on St. Lucia, West Indies

Abstract Few descriptions exist of the nesting behavior of the Gray Trembler (Cinclocerthia gutturalis), and the only nest description of this species seems incongruent with what is known about nesting behavior of other species of Mimidae. We report the first definitively described nest of the Gray Trembler in St. Lucia, West Indies in June–July 2007. We observed construction of, incubation at, and feeding of nestlings in an open-cup nest, similar in architecture to nests of other mimids, contradicting previous reports that Gray Trembler nests are domed, constructed of dried grass, and on top of palm (Cocos nucifera) trees.
