Marsh Birds of the Colorado River Delta

Before the construction of dams and diversions in the Colorado River Basin, the Colorado River Delta in Mexico supported large populations of marsh birds. Pronatura Noroeste in collaboration with partners has been working on a long-term monitoring program and a binational restoration initiative in the Colorado River Delta to protect and conserve this and other groups of birds and their habitats.

Binational Monitoring of Wintering Long-billed Curlews in Mexicali Valley, Mexico

Like many shorebirds, the Long-billed Curlew is a migratory species that faces threats throughout its annual cycle. This project works to connect breeding and non-breeding Long-billed Curlew populations, while also facilitating binational collaborations to work toward a holistic conservation approach.
