COMMON MURRE ( Uria aalge ) 



Status . --Rare winter visitant in coastal waters inshore of the 20 fathom 

 contour. 



Records .— 1 in the Ocean City Inlet (38°20'N, 75°06'W), 29 December 1976; 

 2 at "Jackspot," a shoal fished by sports fishing headboats, 35 km SE Ocean 

 City (38°05'N, 74°46'W), 16 January 1977 (first records for Maryland— Rowlett 

 1978); 1, ca 31 km E Hog Island (37°20'N, 75°20*W), Virginia, 9 February 1976 

 (Philip B. Stanton). 



THICK-BILLED MURRE ( Uria lomvia ) 



Status . --Probably rare and irregular winter visitant over shallow waters 

 inshore from the 30 fathom contour. 



Records .— 1, 70 km ENE Ocean City (38°25'N, 74°24'W), 3 March 1973 

 (Rowlett 1973b); 1 photographed in the surf, 6 km S Ocean City Inlet (38°16'N, 

 75°08'N), along Assateague Island, 9 January 1977 (Rowlett 1978). 



Remarks . — A massive southward migration of thick-billed murres was ob- 

 served along the New England coast during the winter of 1976 - 1977 (Vickery 

 1977). Apparently, the southward advance stopped along the "Cape Cod Front," 

 the leading edge of cold water that flows southward from the Bay of Fundy,
