摘要：With the aim of recovering some unpublished data on a breeding colony of the Brown Booby (Sula leucogaster) at the
Gulf of Urabá we compiled some observations done in October 1977 at the island known as Terrón de Azúcar. At that
time, the colony presented nests with eggs (single and doubled), chicks, fledglings and juveniles. The nests were located
all over the island, from 10 to 50 m above sea level. The total adult population at that time could have been of ca. 400
inds. This small colony of boobies was reported from previous and subsequent observers, but its recent status and
conditions are unknown (at least not published). Some other seabirds (Fregata magnificens and Pelecanus occidentalis)
were also present on the island, but not at reproduction. Some other small islands on the region could harbour small
colonies of seabirds that should be explored.
