On the coast of Labrador, I frequently saw these birds seize flounders on the
edges of the shallows; they often attempted to swallow them whole, but,
finding this impracticable, removed to some rock, beat them, and tore them
to pieces. They appear to digest feathers, bones, and other hard substances
with ease, seldom disgorging their food, unless for the purpose of feeding
their young or mates, or when wounded and approached by man, or when
pursued by some bird of greater power. While at Boston in Massachusetts,
one cold winter morning, I saw one of these Gulls take up an eel, about
fifteen or eighteen inches in length, from a mud bank. The Gull rose with
difficulty, and after some trouble managed to gulp the head of. the fish, and
flew towards the shore with it, when a White-headed Eagle made its appear-
ance, and soon overtook the Gull, which reluctantly gave up the eel, on
which the Eagle glided towards it, and, seizing it with its talons, before it
reached the water, carried it off.
This Gull is excessively shy and vigilant, so that even at Labrador we found it difficult to procure it, nor did we succeed in obtaining more than about a dozen old birds, and that only by stratagem. They watched our movements with so much care as never to fly past a rock behind which one of the party might be likely to lie concealed. None were shot near the nests when they were sitting on their eggs, and only one female attempted to rescue her young, and was shot as she accidentally flew within distance. The time to surprise them was during violent gales, for then they flew close to the tops of the highest rocks, where we took care to conceal ourselves for the purpose. When we approached the rocky islets on which they bred, they left the place as soon as they became aware of our intentions, cackled and barked loudty, and when we returned, followed us at a distance more than a mile.
They begin to moult early in Jul} 1 -. In the beginning of August the young were seen searching for food by themselves, and even far apart. By the 12th of that month they had all left Labrador. We saw them after- wards along the coast of Newfoundland, and while crossing the Gulf of St. Lawrence, and found them over the bays of Nova Scotia, as we proceeded southward. When old, their flesh is tough and unfit for food. Their feathers are elastic, and good for pillows and such purposes, but can rarely be procured in sufficient quantity.
The most remarkable circumstance relative to these birds is, that they either associate with another species, giving rise to a hybrid brood, or that when very old they lose the dark colour of the back, which is then of the same tint as that of the Larus argentatus, or even lighter. This curious fact was also remarked by the young gentlemen who accompanied me to Labrador; and although it is impossible for me to clear up the doubts that
