【 摘 要 】
In the past 20 years, grey seals have become established in coastal waters of the Northeastern United States. There are 3 sites where pupping and breeding occurs in January and February, 2 in Maine and 1 in Massachusetts. In 2002 we recorded a minimum of 1,040 pups born, primarily on Muskeget Island in Massachusetts. Pupping peaks in January on Muskeget Island but is significantly later on the 2 islands in Maine. A total of 3,326 grey seals (adults, juveniles and pups) were counted.
