The Indian grosbeaks are birds of limited distribution; they appear
to be confined to the forests on the higher ranges of the Himalayas.
Their most striking feature is the stout conical bill, which is an
exaggeration of that of the typical finch, and is responsible for
the bird's name. In one genus of grosbeak--_Mycerobas_--the bill is
as deep as it is long, while in the other genus--_Pycnorhamphus_--it
is nearly as massive. Three species belonging to this latter genus
occur in India, namely, _P. icteroides_, the black-and-yellow
grosbeak, found in the Western Himalayas; _P. affinis_, the allied
grosbeak, found in Nepal, Sikkim, Tibet, and Western China; and _P.
carneipes_, the white-winged grosbeak, which occurs all along the
higher Himalayas.
There is only one Indian species of the other genus; this is known
as the spotted-winged grosbeak (_Mycerobas melanoxanthus_), the
localities in which this occurs are said to be "the Himalayas from
the Hazara country to Sikkim at considerable elevations and Manipur."
The only Indian grosbeak which I have met in the flesh is the
yellow-and-black species. This bird is common in the hills round about
Murree, so that, when on ten days' leave there, I had some opportunity
of studying its habits. It is a bird of the same size as the Indian
oriole (_Oriolus kundoo_). The cock grosbeak, indeed, bears a
striking resemblance to the black-headed oriole (_Oriolus
melanocephalus_). His whole head, chin, throat, wings, shoulders,
upper-tail-coverts, and thighs are black, the remainder of the
plumage is a rich yellow, tinged with orange at the hind neck. Thus
the colour and markings are almost identical with those of the
black-headed oriole, the chief difference being that the latter has
a little yellow in the wing. So great is the resemblance that the
casual observer will, in nine cases out of ten, mistake the grosbeak
for an oriole. The resemblance extends to size and shape, as the
following table shows:
Length Length Length Length Length
of Bird. of Tail. of Wing. of Tarsus. of Beak.
Grosbeak . . 9.0 in. 3.7 in. 5.2 in. 1.0 in. 1.0 in.
Oriole . . . 9.5 " 3.4 " 5.4 " 1.0 " 1.3 "
The hen grosbeak differs considerably in colour and marking both from
the cock of her species and from the hen black-headed oriole. She
is a dull ashy-grey bird, tinged faintly with yellowish red on the
back and abdomen. Her wings and tail are black. The only young grosbeak
that I have seen resembled the female in appearance, except that it
had a yellow rump. It was being fed by a cock bird.
