Ceuta Bay is one of the most important sites for the conservation of resident, migratory, and breeding birds in the state of Sinaloa. Pronatura has undertaken studies in the area regarding the reproductive success of two colonies of endangered species: Snowy Plover (Charadrius alexandrinus) and Least Tern (Sterna antillarum). Reproductive success in the area has been around 30% for each species, with 30 plover nests and 150 tern nests. Causes for nest failure include flooding, predation by coyote, bobcats, and Peregrine Falcon, cattle and horse trespassing, and human disturbances. This project aims to increase reproductive success, primarily through the construction of water control mechanisms to control flooding events in the nesting areas. Additionally, a fence will be built to control large mammal and human access to the area. Signs will be posted to inform visitors about the nesting area in order to reduce human intrusion.
