The Puffin or “ Sea Parrot,” as this bird is frequently called, has been 
observed in Pennsylvania only as an accidental winter visitant. But 
one specimen of this species has, so far as I can learn, been captured in 
our state. This bird, now in the possession of Mr. Joseph Krider, of 
Philadelphia, was killed by a gunner in the winter, about 1876, along 
the Delaware river, near Chester city. The Puffins, according to differ- 
ent writers, breed either in crevices of high rocks or cliffs on the sea- . 
coast, or in burrows which they dig in Jhe ground. These holes, it is 
stated, are usually excavated to the depth of about three feet. “ Their 
food consists of various kinds of small fish, particularly sprats, the 
smaller kinds of crabs, shrimps and sea-weeds, and it is not improbable 
but that their sudden migrations are regulated by the presence or ab- 
sence of certain kinds of fish on which they delight to feed.” — Nuttall.

The Black Guillemot, an inhabitant of the dreary coasts and islands 
of the north Atlantic, is a rare and irregular straggler in winter on the 
Atlantic coast, southward to New Jersey. In Pennsylvania this species 
has been observed as an accidental wanderer in winter. A specimen in 
the museum at Lancaster city. Pa., was taken, it is said, on the Susque-
