KITTIWAKE 241 
HYDROCHELIDON NIGRA (Linn.). 
BLACK TERN. 
On 15th October 1903 Mr. E. Turner shot the only 
Manx specimen of this species at the pools on the base of 
Langness. It was an immature specimen with pure white 
underparts, and some mottling of brown on the upper 
plumage (Zool., 1903, p. 460). 
‘The species has ceased to breed in Britain, but is still a 
not infrequent passing migrant, especially in the eastern 
and southern counties of England. Records from Galloway 
are rare, but it has repeatedly occurred in the opposite 
' English counties. In Ireland it is decidedly uncommon, 
but has occurred in Antrim, Down, and especially on 
Dublin Bay.

The species was recorded as a Manx breeding bird by 
Mr, A. G. More, on the authority of Dr. Crellin. There is 
only one colony of the Kittiwake on our coasts, and that a 
comparatively small one. On the Calf of Man, a little east 
of the Stack, a recess in the high sheer cliffs ends in a cave, 
and around the entrance to this the nests are placed on the 
usual little shelves, the lowest being some twenty feet 
above high water. The deep green sea washes up to the 
precipices and covers the floor of the cavern, over the gloom 
of which the beautiful dove-like birds flit like spirits of 
whiteness, A little further to the east is another group of
