THE RAZOR-BILLED AUK. [Razorbill.] |
Genus | ALCA TORDA, Linn. [Alca torda.] |
A few birds of this species occasionally go as far south as New York during winter; but beyond that parallel I never met with one. From Boston eastward
many are seen, and some breed on the Seal Islands off the entrance of the Bay of
Fundy. These Auks generally arrive on our Atlantic coast about the beginning of
November, and return northward to breed about the middle of April. During their
stay with us, they are generally seen singly. and at a greater distance from the
shores than the Guillemots or Puffins; and I have no doubt that they are able to
procure shell-fish at greater depths than these birds. I have observed them
fishing on banks where the bottom was fifteen or eighteen fathoms from the
surface, and, from the length of time that they remained under water, felt no
doubt that they dived to it. On my voyage round Nova Scotia and across the Gulf
of St. Lawrence, we saw some of them constantly. Some had eggs on the
Magdeleine Islands, where, as the inhabitants informed us, these birds arrive
about the middle of April, when the Gulf is still covered with ice. As we
proceeded towards Labrador, they passed us every now and then in long files,
flying at the height of a few yards from the water, in a rather undulating
manner, with a constant beat of the wings, often within musket-shot of our
vessel, and sometimes moving round us and coming so close as to induce us to
believe that they had a wish to alight. The thermometer indicated 44 degrees.
The sight of these files of birds passing swiftly by was extremely pleasing;
each bird would alternately turn towards us the pure white of its lower parts,
and again the jetty black of the upper. As I expected ere many days should pass
to have the gratification of inspecting their breeding-grounds, I experienced
great delight in observing them as they sped their flight toward the north.
After we had landed, we every day procured Auks, notwithstanding their
shyness, which exceeded that of almost all the other sea-birds. The fishermen
having given me an account of their principal breeding places, the Ripley
proceeded toward them apace. One fair afternoon we came in view of the renowned
Harbour of Whapati Guan, and already saw its curious beacon, which, being in
form like a huge mounted cannon placed on the elevated crest of a great rock,
produced a most striking effect. We knew that the harbour was within the
stupendous wall of rock before us, but our pilot, either from fear or want of
knowledge, refused to guide us to it, and our captain, leaving the vessel in
charge of the mate, was obliged to go off in a boat, to see if he could find a
passage. He was absent more than an hour. The Ripley stood off and on, the
yards were manned on the look-out, the sea was smooth and its waters as clear as
crystal, but the swell rose to a prodigious height as it passed sluggishly over
the great rocks that seemed to line the shallows over which we floated. We were
under no apprehension of personal danger, however, for we had several boats and
a very efficient crew; and besides, the shores were within cannon shot; but the
idea of losing our gallant bark and all our materials on so dismal a coast
haunted my mind, and at times those of my companions. From the tops our sailors
called out "Quite shallow here, sir." Up went the helm, and round swung the
Ripley like a duck taken by surprise. Then suddenly near another shoal we
passed, and were careful to keep a sharp look-out until our commander came up.
Springing upon the deck, and turning his quid rapidly from side to side, he
called out, "All hands square the yards," and whispered to me "All's safe, my
good sir." The schooner advanced towards the huge barrier, merrily as a fair
maiden to meet her beloved; now she doubles a sharp cape, forces her way through
a narrow pass; and lo! before you opens the noble harbour of Whapati Guan. All
around was calm and solemn; the waters were smooth as glass, the sails fell
against the masts, but the impetus which the vessel had received urged her
alone. The lead was heaved at every yard, and in a few minutes the anchor was
dropped.
Reader, I wish you had been there, that you might yourself describe the
wild scene that presented itself to our admiring gaze. We were separated from
the rolling swell of the Gulf of St. Lawrence by an immense wall of rock. Far
away toward the east and north, rugged mounds innumerable rose one above
another. Multitudes of frightened Cormorants croaked loudly as they passed us
in the air, and at a distance fled divers Guillemots and Auks. The mossy beds
around us shone with a brilliant verdure, the Lark piped its sweet notes on
high, and thousands of young codfish leaped along the surface of the deep cove
as if with joy. Such a harbour I had never seen before; such another, it is
probable, I may never see again; the noblest fleet that ever ploughed the ocean
might anchor in it in safety. To augment our pleasures, our captain some days
after piloted the Gulnare into it. But, you will say, "Where are the Auks, we
have lost sight of them entirely." Never fear, good reader, we are in a
delightful harbour, and anon you shall hear of them.
Winding up the basin toward the north-east, Captain Emery, myself, and some
sailors, all well armed, proceeded one day along the high and precipitous shores
to the distance of about four miles, and at last reached the desired spot. We
landed on a small rugged island. Our men were provided with long poles, having
hooks at their extremities. These sticks were introduced into the deep and
narrow fissures, from which we carefully drew the birds and eggs. One place, in
particular, was full of birds; it was an horizontal fissure, about two feet in
height, and thirty or forty yards in depth. We crawled slowly into it, and as
the birds affrighted flew hurriedly past us by hundreds, many of their eggs were
smashed. The farther we advanced, the more dismal did the cries of the birds
sound in our ears. Many of them, despairing of effecting their escape, crept
into the surrounding recesses. Having collected as many of them and their eggs
as we could, we returned, and glad were we once more to breathe the fresh air.
No sooner were we out than the cracks of the sailors' guns echoed among the
rocks. Rare fun to the tars, in fact, was every such trip, and, when we joined
them, they had a pile of Auks on the rocks near them. The birds flew directly
towards the muzzles of the guns, as readily as in any other course, and
therefore it needed little dexterity to shoot them.
When the Auks deposit their eggs along with the Guillemots, which they
sometimes do, they drop them in spots from which the water can escape without
injuring them; but when they breed in deep fissures, which is more frequently
the case, many of them lie close together, and the eggs are deposited on small
beds of pebbles or broken stones raised a couple of inches or more, to let the
water pass beneath them. Call this instinct if you will:--I really do not much
care; but you must permit me to admire the wonderful arrangements of that Nature
from which they have received so much useful knowledge. When they lay their
eggs in such an horizontal cavern as that which I have mentioned above, you find
them scattered at the distance of a few inches from each other; and there, as
well as in the fissures, they sit flat upon them like Ducks, for example,
whereas on an exposed rock, each bird stands almost upright upon its egg.
Another thing quite as curious, which I observed, is, that while in exposed
situations the Auk seldom lays more than one egg, yet in places of greater
security I have, in many instances, found two under a single bird. This may
perhaps astonish you, but I really cannot help it.
The Razor-billed Auks begin to drop their eggs in the beginning of May. In
July we found numerous young ones, although yet small. Their bill then scarcely
exhibited the form which it ultimately assumes. They were covered with down,
had a lisping note, but fed freely on shrimps and small bits of fish, the food
with which their parents supply them. They were very friendly towards each
other, differing greatly in this respect from the young Puffins, which were
continually quarrelling. They stood almost upright. Whenever a finger was
placed within their reach, they instantly seized it, and already evinced the
desire to bite severely so cordially manifested by the old birds of this
species, which in fact will hang to your hand until choked rather than let go
their hold. The latter when wounded threw themselves on their back, in the
manner of Hawks, and scratched fiercely with their claws. They walked and ran
on the rocks with considerable ease and celerity, taking to wing, however, as
soon as possible. When thus disturbed while breeding, they fly round the spot
many times before they alight again. Sometimes a whole flock will alight on the
water at some distance, to watch your departure, before they will venture to
return.
This bird lays one or two eggs, according to the nature of the place. The
eggs measure at an average three inches and one-eighth, by two and one-eighth,
and are generally pure white, greatly blotched with dark reddish-brown or black,
the spots generally forming a circle towards the larger end. They differ
considerably from those of the Common and the Thick-billed Guillemots, being
less blunted at the smaller end. The eggs afford excellent eating; the yolk is
of a pale orange colour, the white pale blue. The Eggers collect but few of the
eggs of this bird, they being more difficult to be obtained than those of the
Guillemot, of which they take vast numbers every season.
The food of the Razor-billed Auk consists of shrimps, various other marine
animals, and small fishes, as well as roe. Their flesh is by the fishers
considered good, and I found it tolerable, when well stewed, although it is dark
and therefore not prepossessing. The birds are two years in acquiring the full
size and form of their bill, and, when full grown, they weighed about a pound
and a half. The stomach is an oblong sac, the lower part of which is rather
muscular, and answers the purpose of a gizzard. In many I found scales,
remnants of fish, and pieces of shells. The intestines were, upwards of three
feet in length.
Immediately after the breeding season, these birds drop their quills, and
are quite unable to fly until the beginning of October, when they all leave
their breeding-grounds for the sea, and move southward. The young at this
period scarcely shew the white streak between the bill and the eye; their
cheeks, like those of the old birds at this time, and the fore part of the neck,
are dingy white, and remain so until the following spring, when the only
difference between the young and the old is, that the former have the bill
smaller and less furrowed, and the head more brown. The back, tail, and lower
parts do not seem to undergo any material change.
