Species translocation - capturing animals in one place and releasing them in another—is a widely used conservation method for establishing or reestablishing populations of threatened species. However, translocation projects often fail when the transplanted animals fail to thrive in their new home. A new study from The Condor: Ornithological Applications demonstrates how close monitoring of the animals being released into a new area is helping wildlife managers gauge the success of their effort to save the Ridgway’s Hawk of Hispaniola.
Ridgway’s Hawk is a critically endangered raptor endemic to the Caribbean island of Hispaniola. Since 2009, the Peregrine Fund has translocated 104 nestlings from the species’ stronghold in a national park to a protected resort area called Punta Cana 130 kilometers away. They monitored the birds after their release, tracking their survival and breeding success, as well as collecting the same data on 36–110 breeding pairs per year in the original national park population. Survival rates were high in both locations, and more young hawks began breeding on the resort property, probably because more territories were available due to the birds’ low numbers.
