Figure 19. Seasonal abundance and seav/ard distribution patterns of the 

 pomarine jaegers in the northern Chesapeake Bight, 1971-1977. 



LONG-TAILED JAEGER ( Sterocorarius l ongicaudus ) 



Status . — Rare spring and fall transient. 



R ecords .— SPRING: 1 adult, 126 km ESE Ocean City (38°14'N, 73°40'W), 8 

 May ir77. FALL: 1 adult, 70 km E Ocean City (38°2rN, 74°17'W), 8 August 

 1974. 



Specimen record . --1 adult found dead on beach at Ship Shoal Island, 

 Northamton Co., Virginia, 26 June 1975 (USNM 499381— Williams 1976). 



Remarks . --The distribution of long-tailed jaegers is poorly known in the 

 Atlantic, Wynne-Edwards (1935) suggested that the species is chiefly a migrant 

 over the middle third of the North Atlantic. 



SKUA (C atharacta s^. ) 



Status . --Rare but regular winter visitant, and probably spring transient, 

 occurring chiefly seaward of the 20 fathom contour (54 km offshore) to the 

 Continental Slope (Fig. 20). 



Ea rliest winter record . --4 December 1976, 



Latest s pring r ecord . --8 May 1976 (probably occurs into June).
