AUKS, MURRES, AND PUFFINS 145 
3. Famrty Aucipm. Auxs, Murres, AND Purrins. (Fig. 22c.) 
Twenty-four of the twenty-five species contained in this family 
are North American, and all are confined to the northern parts of the 
Northern Hemisphere. Only seven species are found in the North 
Atlantic, where none nests south of Maine. They are, without excep- 
tion, maritime birds, visiting our bays and harbors at certain seasons, 
but passing much of their lives on the open sea. They go ashore, as arule, 
only to nest, when they gather on islets, often rocky and difficult of 
access, in vast numbers. Puffins stand on the toes and run about 
freely, but the other species rest, like Grebes, on the whole foot and 
tail, and their progress is more awkward. Unlike the Grebes and Loons, 
they use their wings rather than their feet when swimming under water. 
In the air, their flight is direct and rapid, suggesting, in some instances, 
that of a Duck, but the shorter neck should prevent confusion here. 
The Alcide feed on fish, crustacea, sand-eels, and other forms of 
sea life.

One has only to see a Puffin to realize why it is commonly known as 
‘Sea Parrot;’ and when the bird on outstretched, short, rounded wings 
hovers for a moment before alighting, it bears the strongest resemblance
