A well-known colony, of considerable numbers, frequents 
the Farne Islands. 
In Ireland, the Sandwich Tern appears to be very 
locally distributed. The first record of its occurrence was 
made known by Thompson, from a specimen procured on 
Belfast Lough in September, 1832 (Proc. Zool. Soc. Lond., 
1833). From that time little was known of the bird until 
April, 1851, when Mr. Warren observed it in Killala Bay. 
In May, 1857,' he found limited numbers breeding on a small 
lough near Ballina. Recently, viz., July 12th, 1900, the 
same observer discovered twenty pairs of old birds flying 
about an island in Lough Erne, co. Fermanagh. All the 
young were apparently hatched out and ‘had either fled 
out on the lake with the young Black-headed Gulls, or 
concealed themselves among the weeds growing in dense 
thickets about the island.” A young bird, a day or two 
old, examined from this colony, ejected from its gullet a 
sand-eel, which was, in all hkelihood conveyed from the 
sea-coast at a distance of some fifteen miles. Mr. Warren 
states that he did not note these Terns fishing on the 
fresh-water lakes. Two newly-laid eggs and three some- 
what incubated, were found in this locality (‘Irish Natur- 
alist,’ 1900, p. 222). 
On May 24th of this year on an island in Lough 
Conn, the same observer discovered ‘‘on a little space of 
about four yards square,” . . . . ‘thirty-five nests with 
eggs, and two more a little apart from the group of nests. 
Most of the nests had only two eggs, while several had 
only one, evidently showing that the full clutches of three 
had not been laid yet, and also that probably many more 
pairs had not begun to lay so early in the season” 
(‘ Zoologist,’ 1906, p. 278). 
Mr. Warren further writes me that ‘‘ there were on the 
same island a few nests of Common Gulls, which was 
surprising, for the Common Gulls keep away from all the 
others, nesting by themselves on separate islands or on 
isolated rocks.”’ 
This bird is not exclusively marine in its habits, though 
decidedly partial to the sea-coast. Compared with the Com- 
mon, or Arctic Tern, it is much larger and of heavier build. 
To fishermen it is known as the ‘Tern,’ the several smaller 
' But the late Mr. J. J. Watters, of Dublin, appears to have been the 
first to discover it breeding on the Irish Coast, viz., on Rockabill Island, 
July 17th, 1850, where he found a broken egg, and saw three birds.
