BIRDS OF BERMUDA. 269 
Hab.—Nearly cosmopolitan. In North America, chiefly Eastern Uni- 
ted States; not detected on the Pacific side; Patagonia. (Coues). 
One only has occurred, taken alive in the Royal Engineer workshops 
at Boaz Island, on the 29th April, 1875. This bird, which proved to be 
a female, lived only a short time. It is now in Lieutenant Dennison’s 
collection.

These Terns used to visit Bermuda annually and breed in consider- 
able numbers on Gurnet Head Rock and other small islands at the east- 
ern end of the group, but they have now given up their former breeding 
places and are only occasionally seen in the autumn or winter months, 
sometimes in considerable numbers. Doubtless the increase in the pop- 
ulation of the islands and the continual plundering of their nests have 
driven them away. They were sufficiently numerous in 1850, but there 
is no record of their having bred since that date. In 1854 many ap- 
peared in Hamilton Harbor (Hurdis), and in October, 1876, during a 
strong northwest gale, St. George’s Harbor was alive with Terns, Mr. 
Bartram obtaining specimens of the common and black kinds. Nota 
single Tern of any species, to my knowledge, was seen in the autumn 
of 1874 and winter following.
