Birds -- Australia
The mighty Albatross, with its enormous wing-span of possibly up to
14 feet, is also largely a southern bird. That this bird has spread to
the North Pacific Ocean, but has not yet penetrated any distance into
the Atlantic, is another piece of evidence as to the age of these two
oceans. The Pacific Ocean is a very ancient depression, while the
Atlantic is much younger, and has been formed since the lands which
border its shores. The Black-browed Albatross, however, was once seen
in England. Probably this bird might have been carried north on board
ship, and then set free again. Fossil bones of Albatrosses have been
found in France and England. Their remarkable power of wheeling round
and round a vessel, with no perceptible movement of the wing, has
excited much interest and controversy.
Mr. Froude, in his _Oceana_, has given a vivid description of this
flight. The Albatross "wheels in circles round and round and for ever
round the ship--now far behind, now sweeping past in a long, rapid
curve, like a perfect skater on an untouched field of ice. There is no
effort; watch as closely as you will, you rarely or never see a stroke
of the mighty pinion. The flight is generally near the water, often
close to it. You lose sight of the bird as he disappears in the hollow
between the waves, and catch him again as he rises over the crest; but
how he rises, and whence comes the propelling force, are to the
eye inexplicable; he alters merely the angle at which the wings are
inclined...."
Gould considered that many of these birds circumnavigate the globe
many times. They follow ships for days together.
Albatrosses are sometimes caught by those on board ship. One means
of protection employed by these birds is to discharge a considerable
quantity of oily matter at an intruder. This has led sailors to
declare that the bird is "seasick." Some claim that this is not done
for protection, but is due to fright.
The members of the Australasian Ornithologists' Union, when on a trip
in the _Manawatu_ to the Bass Strait Islands found it tantalizing
to see the beautiful Shy Albatrosses sitting on their nests on the
precipitous granite Albatross Rock, and be unable to land owing to the
rough sea that was running. We waited a second and a third day, in the
shelter of Chimney Corner, Three Hummocks Island, but finally had to
depart with but a distant acquaintance with this fine bird. When they
return to nest the succeeding year, the parents drive last year's
brood off the island. Does the young live on its fat all through the
cold, rough winter, or do the parents return at intervals to feed it?
Some recent records by a French party on one of these lonely nesting
islands show that in some cases, at least, the parents do feed the
young at night during their long wait. The sitting bird is fed by
her mate. He opens his mouth, and she inserts her bill, and chooses a
dainty for herself.
