Ma ximum c ounts . --100 feeding in a flock, 94 km ESE Ocean City (38°15'N, 

 74°00"^, 1 June 1575. 



R emarks . --Most sooty shearwaters probably pass through the northern 

 Chesapeake Bight (within a narrow span of time) (Teulings 1972). Few were 

 seen in April, May, and June. They readily respond to chumming, and sometimes 

 get hooked when diving for baited fishing lines.

R emark s. --The Manx shearwater is an inhabitant of cold water zones and in 

 recent years has extended its range across the northern Atlantic to the north- 

 west Atlantic coast (Post 1967). "The first breeding activity in North America 

 was discovered in Massachusetts in 1973 (Bierregaard et al. 1975). This 

 species was first sighted in the northern Chesapeake Biqht off Maryland in
