say that the flesh of these birds, when cooked, is quite
white, and very good eating; but bold must the man be who
attempts such a meal.

We have now only to mention the turkey-buzzard (Vultur
aura), and the Gallinazo. The former is found wherever
the country is moderately damp, from Cape Horn to North
America. Differently from the Polyborus Brasiliensis and
Chimango, it has found its way to the Falkland Islands. The
turkey-buzzard is a solitary bird, or at most goes in pairs. It
may at once be recognised from a long distance, by its lofty,
soaring, and most elegant flight. It is well known to be a
true carrion-feeder. On the west coast of Patagonia, among
the thickly-wooded islets and broken land, it lives exclusively
on what the sea throws up, and on the carcasses of dead
seals. Wherever these animals are congregated on the rocks,
there the vultures may be seen. The Gallinazo (Cathartes
atratus) has a different range from the last species, as it
never occurs southward of lat. 41 degs. Azara states that
there exists a tradition that these birds, at the time of the
conquest, were not found near Monte Video, but that they
subsequently followed the inhabitants from more northern
districts. At the present day they are numerous in the valley
of the Colorado, which is three hundred miles due south of Monte
Video. It seems probable that this additional migration has
happened since the time of Azara. The Gallinazo generally
prefers a humid climate, or rather the neighbourhood of
fresh water; hence it is extremely abundant in Brazil and
La Plata, while it is never found on the desert and arid
plains of Northern Patagonia, excepting near some stream.
