Uria grylle, Zinn. BLACK GUILLEMOT. 
A few pairs breed on Shieldaig Island, Eilean Mhor, 
and probably on the other islands and shores of Loch 
Torridon. 
Fratercula arctica (Zinn.). PUFFIN. 
Present in large numbers on Loch Torridon in July and 
August. These birds have probably come in from the 
Shiant Islands, where there is the largest “puffinery” in 
Britain. See also our remarks under Razorbill. 
Colymbus glacialis, Zinn. GREAT NORTHERN DIVER. 
Winter and spring visitant. Rare. 
Colymbus arcticus, Zinn. BLACK-THROATED DIVER. 
Breeds on several lochs in Gairloch, and at least one 
locality in Applecross. 
Colymbus septentrionalis, Zinn. RED-THROATED DIVER. 
Thinly distributed throughout the district, and perhaps 
more abundant towards the south than C. arcticus. At least 
three pairs nesting in Applecross in 1892, in all cases on 
islets in small lochs. 
Podicipes auritus (Zinn.). SCLAVONIAN GREBE. 
A fine specimen of this Grebe, just assuming summer 
plumage, killed by Donald Matheson at Shieldaig in 
March 1893, is now in the Museum of Science and Art, 
Edinburgh. 
- 
Podicipes fluviatilis (Zunstall), LITTLE GREBE. 
Not common and local. Nested at Diabaig in 1891, and 
breeds on other lochs inthe district.
