Craveri’s Murrelet breeds on a total of ten islands in the Gulf of California and off the Pacific Coast of Baja California. It winters off the coast to southern California and south as far as Guatemala.


Craveri’s and Xantus’ Murrelets are very similar, and it can be difficult to tell the two apart species when seen at sea.


There are about 5,000 breeding pairs; including pre-breeding birds, there are as many as 15,000-20,000 birds total. Populations of this murrelet are presumed to be declining rapidly due to the presence of introducted mammalian predators on their breeding islands; but recently, a management plan has been developed that elimiates these predators from islands that are present, past or potential breeding sites.


Other management plans have been developed for all ten breeding islands that protect nesting areas against trespass, provide environmental education programs, and enforce existing regulations.


Additional threats to the Craveri's Murrelet include oil pollution from offshore wells and ships, and mortality from gill-nets.
