摘要
We studied the breeding phenology of a colony of Boat-billed Herons (Cochlearius cochlearius) on the Caribbean slope of Costa Rica during 1999. Breeding season lasted from early February to July and two periods of nesting were recorded, strongly suggesting the occurrence of double-brooding. Clutches from the first and the second period started during the dry season, but clutches from the second period developed during the rainy period.
