Research Interests & Background

Osvel Hinojosa-Huerta is interested in bird conservation with emphasis on coastal and wetland areas, and in evaluating the effectiveness of conservation mechanisms, restoration actions and environmental policy decisions. His research has been centered in assessing the response of bird populations to riparian and wetland restoration, studying the long-term effects of drought and instream flow reductions on bird communities, and in identifying conservation needs and opportunities for marsh birds in the Colorado River delta. He was the Director of the Water and Wetlands Program for Pronatura Noroeste in Mexico, where he led the efforts to restore the Colorado River delta for over 20 years, including the restoration of river flows and the facilitation of binational negotiations between Mexico and the US for the Colorado River. Currently he is leading efforts to create capacity for shorebird conservation along the Pacific Flyway from Mexico to Chile, supporting emerging leaders from Latin America through a fellowship program at the Cornell Lab of Ornithology. He obtained a BSc in Biochemical Engineering and Marine Sciences from ITESM Campus Guaymas and a Ph.D. in Wildlife and Fisheries Science from the University of Arizona.
