It is my intention to classify the Zucans, ‘so called by the Guaranis,’ amongst the diurnal birds of

yrey, although nature seems to have unj 1 a character ,
prey, g ave united in them a character and figure altogether opposed to a cruel

and sanguinary appetite. They are nearly always gregarious, since it is usual to meet them in a family
party or congregated in little troops.

They have very short wings and a misshapen beak, incapable of the operations of bending, sawing

or grinding. The legs cannot be advanced alternately, but only by forced jumps. The two hind-claws are
quite useless for seizure, attack or defence.

The Toucans, contrary to all appearances, destroy a great number of birds, and on account of their

large and strong beak are respected and feared by all species. They attack and drive them from their

nests, and in their very presence eat their eggs and young; these they draw from the holes with the long
beak, or throw down nest and all together.

“It is credibly reported that the Toucans do not even respect the eggs or young of the ‘ Aras’ and
‘ 7 w¥Cier. 1 line . OF e ie
Caracaras ;’ and if the fledglings are too large or too strong to be lifted from the nest, they dash them

to the ground, as if it were their nature not only to devour but to uselessly destro

y.

‘The solid nest of the White Ant, that resists the action of the weather and other destructive
causes, is not proof against the Toucan’s attack, for he waits until the clay of which the nest is formed is
moistened by the rain, and then breaks it up with his beak so as to obtain the eggs and young ants ; in fact
during the breeding season the Toucan feeds upon nothing else; the rest of the year is for him a long
fast, so strict, that he can only get fruits with sometimes a few insects and buds of trees, nor does he
continue to annoy other birds. It is my opinion that the Toucans are unable to catch adult birds; but
supposing they were, their stomach would not be capable of digesting the feathers and bones, nor their
bill of plucking and disjointing. But in order not to deviate in any respect from the truth, I confess that I
I am not sure that the small species of Toucans do not break the nests and devour the young ones, because,
being more rare than the others in Paraguay, I have not been able to verify the fact, although I do not
doubt it; for having the same form and the same manner of living, they must have the same habits.

“In the first two species the bill is out of all proportion. The bird in flying presents the point of it
to the wind, so that it does not offer more resistance than that of other birds in which the head and
superficies are equal in extent; besides which, the conformation and specific lightness of this long beak
cannot impede flight, because the highest points of the bird being the bill itself and the anterior portion
of the body, they form no obstacle, the wind first taking effect upon the point of the bill: when in a state
of repose, the Toucan carries its bill rather more elevated than a horizontal-line that would pass through
the eyes, and when closely looked at it appears like a false bill, because its base exceeds the breadth
of the head, which presents the appearance of being enclosed in a case.

“Tn addition to these singularities, the nostrils are placed behind the aforesaid base.

“The tongue is very narrow and of an equal thickness throughout; it is entirely osseous, and

resembles somewhat a feather two lines in width furnished with an osseous fringe, which is directed from
