Provide artificial nesting sites for oilbirds
A before-and after-study at a colony of oilbirds Steatornis capripensis nesting in a cave at the Asa Wright Nature Center, Trinidad (Lambie 1993), found that the population increased from 25-30 birds to more than 100 individuals and 43 nests by 1977 following the installation of artificial concrete ledges in 1967-1968. Before this, the colony appeared limited in size by the 15 or 16 ledge nest sites available. In 1977, 21 of the nests were on artificial ledges.
