| Abstract: | The effectiveness of 17 yr of nestguarding from observation blinds for increasing reproductive success of the endangered Puerto Rican Parrot (Amazona vittata) is described. As personnel and time allowed, active nests were guarded part-time during the nest site exploration and selection s stage of the breeding cycle, and part-time to full-time when a nest contained eggs or chicks. Biologists identified nine categories of threat to the success of parrot nests. Since 1973, a minimum of 20 nests, which otherwise would have failed, successfully produced fledglings as a direct result of nest guarding and intervention. Nest success averaged 66% with nest guarding compared to an estimated 38% without guarding. Nest guarding from blinds can help maintain a wild population of a critically endangered species while other management techniques are being developed to stimulate population growth. |
