COMMON PUFFIN. 
When living, these Auks are particularly trim and elegantly formed birds, for they sit 
upright, resting upon the tarsi, and keep themselves very clean with the feathers perfectly 
smooth and glossy. The Razor-bills are inclined to be quarrelsome birds, especially with 
other species, and they would seldom allow a Puffin or Murre to alight very near them, 
opening their bills at the intruder, and disclosing the bright orange mouth. The eyes of 
the Razor-bills, when examined carefully, are peculiar, as the edge of the iris, next ther 
pupil, is scalloped, not perfectly circular as ordinarily. The Razor-billed Auks not only 
dive but swim well, and ride lightly on the water. The eggs are deposited during the last 
week in July, and the birds migrate southward late in October. 
GENUS n. MORMON. THE PUFFINS.

HABITS. 
[ found these odd, little Puffins nesting on the face of the high cliffs on Bryon Is¬ 
land, but on Bird Rock, they dug their burrows on the surface, often excavating beneath 
aflat slab of limestone, with which a portion of the rock was strewed. The burrows were 
about six inches in diameter, usually turned either to the right or left, and were from two 
to six feet long; but the terminus which was slightly enlarged, was never very far from the 
surface. The single egg was placed in this chamber and was always covered by either 
the male or female Puffin, which bravely resisted my efforts to remove the egg, biting 
fiercely; and as these birds are endowed with the same tenacity of purpose which charac¬ 
terizes a snapping turtle, I would frequently withdraw my hand with a Puffin attached to 
one finger. When brought to the surface, however, and allowed to escape, they would 
mount into air, and darting downward, would fly out to sea; but if held in the hand, would 
struggle constantly, uttering a croaking sound. 
The Puffins are quite unsuspicious, aud during foggy mornings, when all the species 
which inhabit the Rock, are much tamer than at other times, they would permit me to ap¬ 
proach very near them. Indeed I have often seated myself upon a rock on the breeding 
ground, when several of the little red-beaked fellows would alight within three or four feet 
of me, and I could thus observe their habits very closely. They fly with exceeding swift¬ 
ness, but when about to settle, the speed is checked, the feet which in air are held hori-
