Molting phenology of the Pacific harbor seal ( Phoca vitulina richardii) on two islands off the Baja California Peninsula, Mexico
Abstract We document and compare the annual molt of the Pacific harbor seal ( Phoca vitulina richardii ) on two islands off the west coast of the Baja California Peninsula that are the northern and southern extremes of its distribution in Mexico. During 2014, observations were made from March to Jul...
