Conservation status of Craveri’s murrelet in Mexico

Yuliana Rocío Bedolla Guzmán

The Craveri’s murrelet (CRMU; Synthliboramphus craveri) is an endemic species of Mexico, listed as Vulnerable in the IUCN Red List. This small alcid breeds on islands in the Gulf of California and in the Mexican Pacific Ocean. Historically, invasive mammals have been the main threat for this species that caused colony extirpation on some islands. Currently, conservation status of CRMU in the Gulf of California is uncertain. The objective of this project is to assess the breeding status of the species and identify the presence of invasive mammals on historical and potential breeding islands. We will work on nine islands in the zone of Midriff islands: Estanque, Partida, Rasa, Las Ánimas, Salsipuedes, San Pedro Mártir, Choyudo, Dátil and Alcatraz. We will perform nests searching, capturing individuals and vocalizations recording to evaluate the presence of CRMU. We will install traps and camera traps to assess the presence of invasive mammals. We will give outreach talks at two local communities about the importance of CRMU and island biosecurity to prevent the introduction of invasive species. The final product will be an action plan with conservation and restoration actions for the species. This project will contribute to improve conservation management decisions in the region.
