Chile, they haunt, during the greater part of the year, the
lower country near the shores of the Pacific, and at night
several roost together in one tree; but in the early part of
summer, they retire to the most inaccessible parts of the
inner Cordillera, there to breed in peace.

With respect to their propagation, I was told by the
country people in Chile, that the condor makes no sort of
nest, but in the months of November and December lays
two large white eggs on a shelf of bare rock. It is said that
the young condors cannot fly for an entire year; and long
after they are able, they continue to roost by night, and
hunt by day with their parents. The old birds generally live
in pairs; but among the inland basaltic cliffs of the Santa
Cruz, I found a spot, where scores must usually haunt. On
coming suddenly to the brow of the precipice, it was a grand
spectacle to see between twenty and thirty of these great
birds start heavily from their resting-place, and wheel away
in majestic circles. From the quantity of dung on the rocks
they must long have frequented this cliff for roosting and
breeding. Having gorged themselves with carrion on the
plains below, they retire to these favourite ledges to digest
their food. From these facts, the condor, like the gallinazo,
must to a certain degree be considered as a gregarious bird.
In this part of the country they live altogether on the guanacos
which have died a natural death, or as more commonly
happens, have been killed by the pumas. I believe, from
what I saw in Patagonia, that they do not on ordinary occasions
extend their daily excursions to any great distance
from their regular sleeping-places.
