Overview
Raptors play critical roles as apex predators in ecosystems around the world, yet many species face significant conservation challenges. My research focuses on assessing global raptor populations, identifying conservation priorities, and developing evidence-based strategies to protect these magnificent birds.
Global Assessments
I lead efforts to understand the status of raptors at continental and global scales. This work involves synthesizing data from multiple sources, collaborating with researchers worldwide, and applying quantitative methods to identify species and regions of greatest conservation concern. The landmark publication "State of the World's Raptors" represents a comprehensive assessment of raptor distributions, threats, and conservation actions globally.
Conservation Priorities
Not all species face equal threats, and conservation resources are limited. My research develops frameworks for prioritizing conservation efforts based on extinction risk, evolutionary distinctiveness, and feasibility of conservation action. This work has identified the world's most imperiled raptors and highlighted regions where conservation investment is most urgently needed.
Island Endemics
Island-endemic raptors face particularly acute threats due to small population sizes, limited ranges, and vulnerability to invasive species. I have worked extensively on conservation of species like the Ridgway's Hawk in the Dominican Republic, contributing to successful population recovery through translocation and management programs.
