68 RESIDENTS AND MIGRANTS. 
GOOSANDER. Mergus merganser, Linneus. 
A winter visitant to England and Ireland. Of more 
frequent occurrence in Scotland, and said to breed 
in the Hebrides*; although Capt. Elwes, who spent 
two months in the Hebrides during the nesting- 
season of 1868, made special search for this species 
without seeing itf; and Capt. Feilden and Mr. Harvie 
Brown, who visited the Long Island in the summer 
of 1870, were also unsuccessful in their search for it. 
Dr. Dewar, however, found it breeding in North 
Uist in 1858, and shot a female off the nest{. In 
May 1871, Mr. Harvie Brown received fresh eggs of 
this bird from the north of Perthshire. ‘The nest, as 
he informs me, was placed in the hollow of an old 
tree; and the eggs were taken on or about the 20th 
of May. 
Fam. COLYMBID &. 
GREAT NORTHERN DIVER. Colymbus glacialis, Lin- 
neus. 
A winter visitant, a few remaining throughout the 
summer in Ireland and the Hebrides. The nest, 
however, has not been found in the British Islands.
