This Parrot, called in La Plata the Bank- or Burrowing-Parrot, from its

nesting-habits, is the only member of its order found so far south as

Patagonia. In habits it differs somewhat from most of its congeners,

and it may be regarded, I think, as one of those species which are

dying out--possibly owing to the altered conditions resulting from the

settlement of the country by Europeans. It was formerly abundant on the

southern pampas of La Plata, and being partially migratory its flocks

ranged in winter to Buenos Ayres, and even as far north as the Paraná

river. When, as a child, I lived near the capital city (Buenos Ayres),

I remember that I always looked forward with the greatest delight to

the appearance of these noisy dark-green winter visitors. Now they

are rarely seen within a hundred miles of Buenos Ayres; and I have

been informed by old gauchos that half a century before my time they

invariably appeared in immense flocks in winter, and have since

gradually diminished in numbers, until now in that district the

Bank-Parrot is almost a thing of the past. Two or three hundred miles

south of Buenos Ayres city they are still to be met with in rather large

flocks, and have a few ancient breeding-places, to which they cling very

tenaciously. Where there are trees or bushes on their feeding-ground

they perch on them; they also gather the berries of the _Empetrum

rubrum_ and other fruits from the bushes; but they feed principally on

the ground, and, while the flock feeds, one bird is invariably perched

on a stalk or other elevation to act as sentinel. They are partial

to the seeds of the giant thistle (_Carduus mariana_), and the wild

pumpkin, and to get at the latter they bite the hard dry shell into

pieces with their powerful beaks. When a horseman appears in the

distance they rise in a compact flock, with loud harsh screams, and

hover above him, within a very few yards of his head, their combined

dissonant voices producing an uproar which is only equalled in that

pandemonium of noises, the Parrot-house in the Zoological Gardens of

London. They are extremely social, so much so that their flocks do not

break up in the breeding-season; and their burrows, which they excavate

in a perpendicular cliff or high bank, are placed close together;

so that when the gauchos take the young birds--esteemed a great

delicacy--the person who ventures down by means of a rope attached to

his waist is able to rifle a whole colony. The burrow is three to five

feet deep, and four white eggs are deposited on a slight nest at the

extremity. I have only tasted the old birds, and found their flesh very

bitter, scarcely palatable.

The natives say that this species cannot be taught to speak; and it

is certain that the few individuals I have seen tame were unable to

articulate.

Doubtless these Parrots were originally stray colonists from the

tropics, although now resident in so cold a country as Patagonia. When

viewed closely, one would also imagine that they must at one time have

been brilliant-plumaged birds; but either natural selection, or the

direct effect of a bleak climate, has given a sombre shade to their

colours--green, blue, yellow, and crimson; and when seen flying at a

distance, or in cloudy weather, they look as dark as crows.
