BLACK GUILLEMOT.

much more shy and wary than the other Guillemots. The 
eggs (called improperly those of the Noddy) are brought 
sometimes in small coasting-vessels to Boston market. 
There are two races of the Sea Pigeon in our fauna, — for 
jVJandt’s Guillemot is only a Northern race or variety of the pres- 
ent species, — and of these the Black Guillemot is the more south- 
ern in distribution, breeding from the Bay of B'undy to southern 
Labrador. In winter it is rather common oti the New England 
shores, and a few examples wander as far south as New Jersey. 
I did not find the.se birds as shy as Nuttall’s statement led me to 
anticipate. They were .somewhat wary and alert, but allowed me 
to paddle within easy shooting distance without displaying much 
alarm. When they finally concluded that I was an unsafe neigh- 
bor, they lost no time in getting out of my sight, diving with sur- 
prising suddenness. They usually swam a long distance under 
water with great rapidity, using their wings as well as feet, and 
coming to the surface far beyond gunshot range. 
The Sea Pigeons are met usually in small flocks of half a 
dozen or more, and generally feed in the open sea at the base of 
bold cliffs. When on the wing they proceed rapidly and in a 
straight line, and rarely more than a few feet from the surface 
of the water. On approching their nesting-site they rise rather 
abruptly, and fly directly to their nests. 
Note. — Mandt’s Guii.lemot (C. mandtii) is a northern variety 
of the Sea Pigeon, differing from grylle in lacking the black bar 
on the wing-patch, and having a somewhat stouter bill. It breeds 
from high Arctic regions to the coast of Labrador and Hudson Bay, 
and in winter may be found off the Atlantic shores from south 
Greenland to New Jersey, though it is not at all common along 
the southern portion of its range. 
The Black-winged Guillemot (C. motzfeldi) is said to occur 
on the shores of Cumberland Bay and in Greenland.
