this is the most abundant. At Port Desire I found its nest: egg,
about .83 in length; form somewhat more elongated than in that of the
last species; colour, pale green, almost obscured by minute freckles and
clouds of pale dull red.

This bird is very common on the coast of Chile, from the humid forests
of Chiloe to the desert mountains of Copiapó. In Chiloe it is perhaps
the most abundant of the land birds; south of Chiloe I never saw it,
although the nature of the country does not change them. On the eastern
side of the continent, I met with this bird only at the Rio Negro, in
northern Patagonia. I do not believe it inhabits the shores of the
Plata, although so common in the open country, under corresponding
latitudes west of the Cordillera. The Diuca, as this Fringilla is called
in Chile, generally moves in small flocks, and frequents, although not
exclusively, cultivated ground in the neighbourhood of houses: habits
very similar to those of the _Zonotrichia matutina_. During incubation,
the male utters two or three pleasing notes, which Molina has in an
exaggerated description called a fine song. In October, at Valparaiso, I
found the nest of this bird in the trellis-work of a vineyard, close by
a much frequented path. The nest is shallow, and about six inches
across; the outer part is very coarse, and composed of the thin stalks
of twining plants, strengthened by the husky calices of a composite
flower; this outside part is lined by many pieces of rag, thread,
string, tow, and a few feathers. Eggs rather pointed, oval, ·94 of an
inch in length; colour, pale dirty green, thickly blotched by rather
pale dull brown, which small blotches and spots become confluent, and
entirely colour the broad end.

This finch is common on the outskirts of the forests in Tierra del

is much smaller, and is richer in its colouring.

I obtained specimens of this bird from Northern Chile, and Southern
Patagonia. I saw it also in the Cordillera of Central Chile, at an
elevation of at least eight thousand feet, near the upper limit of
vegetation. In Patagonia it is not common, it frequents bushy valleys in
small flocks, from six to ten in number. These birds sometimes move from
thicket to thicket with a peculiar soaring flight: they occasionally
utter very singular and pleasing notes.

This species is common at the Falkland Islands, and it often occurs
mingled in the same flock with the last one. I suspect, however, it more
commonly frequents higher parts of the hills. These species have a very
close general resemblance; but the marks about the head, which are white
in the _C. melanodera_, are yellow in the _C. xanthogramma_, while the
parts of the tail-feathers which are white in the latter, are yellow in
the _C. melanodera_: this difference of colours does not hold in the
females, but they may be at once distinguished by the greater length of
wing, when folded, of the _C. xanthogramma_.

This singular genus[13] appears to be confined to the islands of the
Galapagos Archipelago. It is very numerous, both in individuals and in
species, so that it forms the most striking feature in their
ornithology. The characters of the species of Geospiza, as well as of
the following allied sub-genera, run closely into each other in a most
remarkable manner.
In my Journal of Researches, p. 475, I have given my reasons for
believing that in some cases the separate islands possess their own
representatives of the different species, and this almost necessarily
would cause a fine gradation in their characters. Unfortunately I did
not suspect this fact until it was too late to distinguish the specimens
from the different islands of the group; but from the collection made
for Captain FitzRoy, I have been able in some small measure to rectify
this omission.
In each species of these genera a perfect gradation in colouring might,
I think, be formed from one jet black to another pale brown. My
observations showed that the former were invariably the males; but Mr.
Bynoe, the surgeon of the Beagle, who opened many specimens, assured me
that he found two quite black specimens of one of the smaller species of
Geospiza, which certainly were females: this, however, undoubtedly is an
exception to the general fact; and is analogous to those cases, which
Mr. Blyth[14] has recorded of female linnets and some other birds, in a
state of high constitutional vigour, assuming the brighter plumage of
the male. The jet black birds, in cases where there could be no doubt in
regard to the species, were in singularly few proportional numbers to
the brown ones: I can only account for this by the supposition that the
intense black colour is attained only by three-year-old birds. I may
here mention, that the time of year (beginning of October) in which my
collection was made, probably corresponds, as far as the purposes of
incubation are concerned, with our autumn. The several species of
Geospiza are undistinguishable from each other in habits; they often
form, together with the species of the following sub-genera, and
likewise with doves, large irregular flocks. They frequent the rocky and
extremely arid parts of the land sparingly covered with almost naked
bushes, near the coasts; for here they find, by scratching in the
cindery soil with their powerful beaks and claws, the seeds of grasses
and other plants, which rapidly spring up during the short rainy season,
and as rapidly disappear. They often eat small portions of the succulent
leaves of the _Opuntia Galapageia_, probably for the sake of the
moisture contained in them: in this dry climate the birds suffer much
from the want of water, and these finches, as well as others, daily
crowd round the small and scanty wells, which are found on some of the
islands. I seldom, however, saw these birds in the upper and damp
region, which supports a thriving vegetation; excepting on the cleared
and cultivated fields near the houses in Charles Island, where, as I was
informed by the colonists, they do much injury by digging up roots and
seeds from a depth of even six inches.
