Bills. This Fact I Repeatedly Saw, As, Like Swallows, They
Continued To Fly Backwards And Forwards Close Before Me.
Occasionally When Leaving The Surface Of The Water Their
Flight Was Wild, Irregular, And Rapid; They Then Uttered Loud
Harsh Cries.
When these birds are fishing, the advantage
of the long primary feathers of their wings, in keeping them
dry, is very evident.
When thus employed, their forms resemble
the symbol by which many artists represent marine
birds. Their tails are much used in steering their irregular
course.
These birds are common far inland along the course of
the Rio Parana; it is said that they remain here during the
whole year, and breed in the marshes. During the day they
rest in flocks on the grassy plains at some distance from
the water. Being at anchor, as I have said, in one of the
deep creeks between the islands of the Parana, as the evening
drew to a close, one of these scissor-beaks suddenly appeared.
The water was quite still, and many little fish were
rising. The bird continued for a long time to skim the
surface, flying in its wild and irregular manner up and down
the narrow canal, now dark with the growing night and the
shadows of the overhanging trees. At Monte Video, I observed
that some large flocks during the day remained on the
mud-banks at the head of the harbour, in the same manner
as on the grassy plains near the Parana; and every evening
they took flight seaward. From these facts I suspect
that the Rhynchops generally fishes by night, at which time
many of the lower animals come most abundantly to the
surface. M. Lesson states that he has seen these birds
opening the shells of the mactrae buried in the sand-banks on
the coast of Chile: from their weak bills, with the lower
mandible so much projecting, their short legs and long
wings, it is very improbable that this can be a general habit.
In our course down the Parana, I observed only three
other birds, whose habits are worth mentioning. One is a
small kingfisher (Ceryle Americana); it has a longer tail
than the European species, and hence does not sit in so stiff
and upright a position. Its flight also, instead of being direct
and rapid, like the course of an arrow, is weak and
undulatory, as among the soft-billed birds. It utters a low
note, like the clicking together of two small stones. A small
green parrot (Conurus murinus), with a grey breast, appears
to prefer the tall trees on the islands to any other
situation for its building-place. A number of nests are
placed so close together as to form one great mass of sticks.
These parrots always live in flocks, and commit great ravages
on the corn-fields. I was told, that near Colonia 2500 were
killed in the course of one year. A bird with a forked tail,
terminated by two long feathers (Tyrannus savana), and
named by the Spaniards scissor-tail, is very common near
Buenos Ayres: it commonly sits on a branch of the _ombu_
tree, near a house, and thence takes a short flight in pursuit
of insects, and returns to the same spot. When on the wing
it presents in its manner of flight and general appearance
a caricature-likeness of the common swallow. It has the
power of turning very shortly in the air, and in so doing
opens and shuts its tail, sometimes in a horizontal or lateral
and sometimes in a vertical direction, just like a pair of
scissors.
October 16th. - Some leagues below Rozario, the western
shore of the Parana is bounded by perpendicular cliffs,
which extend in a long line to below San Nicolas; hence it
more resembles a sea-coast than that of a fresh-water river.
It is a great drawback to the scenery of the Parana, that,
from the soft nature of its banks, the water is very muddy.
The Uruguay, flowing through a granitic country, is much
clearer; and where the two channels unite at the head of
the Plata, the waters may for a long distance be distinguished
by their black and red colours. In the evening, the
wind being not quite fair, as usual we immediately moored,
and the next day, as it blew rather freshly, though with a
favouring current, the master was much too indolent to think
of starting. At Bajada, he was described to me as "hombre
muy aflicto" - a man always miserable to get on; but certainly
he bore all delays with admirable resignation. He
was an old Spaniard, and had been many years in this
country. He professed a great liking to the English, but
stoutly maintained that the battle of Trafalgar was merely
won by the Spanish captains having been all bought over;
and that the only really gallant action on either side was
performed by the Spanish admiral. It struck me as rather
characteristic, that this man should prefer his countrymen
being thought the worst of traitors, rather than unskilful or
cowardly.
18th and 19th. - We continued slowly to sail down the
noble stream: the current helped us but little. We met,
during our descent, very few vessels. One of the best gifts
of nature, in so grand a channel of communication, seems
here wilfully thrown away - a river in which ships might
navigate from a temperate country, as surprisingly abundant
in certain productions as destitute of others, to another
possessing a tropical climate, and a soil which, according to
the best of judges, M. Bonpland, is perhaps unequalled in
fertility in any part of the world. How different would
have been the aspect of this river if English colonists had
by good fortune first sailed up the Plata! What noble towns
would now have occupied its shores! Till the death of
Francia, the Dictator of Paraguay, these two countries must
remain distinct, as if placed on opposite sides of the globe.
And when the old bloody-minded tyrant is gone to his long
account, Paraguay will be torn by revolutions, violent in
proportion to the previous unnatural calm.
