THE MANX SHEARWATER. 
413 
Sir William Jardine observes— the Calf of Man u becoming 
more frequented, and a light-house being erected, the birds dis- 
appeared entirely, and on a visit which we made to this interest- 
ing island, we were much disappointed in scarcely being able to 
trace even the recollection of their former abundance. - ”* Although 
the species which derives its name from the island has deserted it, 
there is still great abundance of other sea-fowl there in the breed- 
ing season, as I had an opportunity of witnessing on the 21st of 
May, 1826, when proceeding from Belfast to Liverpool in the 
Chieftain steam-ship. It was so beautifully calm and serene, that 
we sailed between the Isle of Man and the Calf, keeping but a few 
yards from the latter, which contains two handsome lighthouses, 
both built on the same plan, with an excellent dwelling-house in 
modern taste attached to each. Between the Calf and a rock at 
some distance from the shore, the run of the tides was very strong, 
but the sea, nevertheless, did not lose its smoothness, and it was 
most interesting to observe fishes .leaping in every direction, and 
sea-fowl of various species (chiefly common guillemots and razor- 
bills), diving and sporting around. The Calf of Man is girt by 
cliffs, in some places lofty and perpendicular, but the most pictu- 
resque rocks are those that stand apart, one of which has an 
arch opening entirely through it. 
At the Scilly Islands the Manx shearwater continues to breed ; 
a full and^excellentjaccount of it, as observed at the barren island 
of Annet, one of the group, was contributed by Mr. D. W. Mit- 
chell to Yarrell's f British Birds/ The species is said also to 
breed on some of the Hebrides, Orkney, and Shetland Isles. 
This shearwater is but an accidental visitant to the North Ame- 
rican coast (Bonaparte). 
Authors have often described flocks of birds which keep 
flying all day over the Dardanelles and Bosphorus, and are never 
seen to alight either for rest or food ; but only of late was 
their species positively determined. As remarked in Walsh's 
* ‘ Brit. Birds/ vol. iv. p. 255.
