BIRDS OF BERMUDA. 269 



Hob. — Nearly cosmopolitan. lu North America, chiefly Eastern Uni- 

 ted Statei^; not detected on the Pacific side; Patagonia. (Coues). 



One only has occurred, taken alive in the Koyal 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. Not a 

 single Tern of any species, to my knowledge, was seen in the autumn 

 of 1874 and winter following.
