it destroys young lambs by tearing the umbilical cord; and
that it pursues the Gallinazo, till that bird is compelled to
vomit up the carrion it may have recently gorged. Lastly,
Azara states that several Carranchas, five or six together,
will unite in chase of large birds, even such as herons. All
these facts show that it is a bird of very versatile habits and
considerable ingenuity.

The Polyborus Chimango is considerably smaller than the
last species. It is truly omnivorous, and will eat even bread;
and I was assured that it materially injures the potato crops
in Chiloe, by stocking up the roots when first planted. Of
all the carrion-feeders it is generally the last which leaves
the skeleton of a dead animal, and may often be seen within
the ribs of a cow or horse, like a bird in a cage. Another
species is the Polyborus Novae Zelandiae, which is exceedingly
common in the Falkland Islands. These birds in many
respects resemble in their habits the Carranchas. They live
on the flesh of dead animals and on marine productions; and
on the Ramirez rocks their whole sustenance must depend
on the sea. They are extraordinarily tame and fearless, and
haunt the neighborhood of houses for offal. If a hunting
party kills an animal, a number soon collect and patiently
await, standing on the ground on all sides. After eating,
their uncovered craws are largely protruded, giving them a
disgusting appearance. They readily attack wounded birds:
a cormorant in this state having taken to the shore, was
immediately seized on by several, and its death hastened
by their blows. The Beagle was at the Falklands only
during the summer, but the officers of the Adventure, who
