GULLS) AND) TERNS, 59 
called in the fens, belongs to the group known as 
Marsh Terns—birds that rarely frequent the sea 
coast at all, so that its absence from our avi-fauna, 
although greatly to be deplored, could scarcely 
be remarked by the observer of marine species 
alone. The White-winged Black Tern and the 
Whiskered Tern complete this division, known as 
“Marsh Terns.” Both these latter are occasional 
wanderers to the British Islands.
