ing a hood; wings and tail long; beak moderately
short._

This pigeon can at once be recognised by its hood, almost enclosing the
head and meeting in front of the neck. The hood seems to be merely an
exaggeration of the crest of reversed feathers on the back of the head,
which is common to many sub-varieties, and which in the Latz-taube[294]
is in a nearly intermediate state between a hood and a crest. The
feathers of the hood are elongated. Both the wings and tail are
likewise much elongated; thus the folded wing of the Jacobin, though a
somewhat smaller bird, is fully 11/4 inch longer than in the rock-pigeon.
Taking the length of the body without the tail as the standard of
comparison, the folded wing, proportionally with the wings of the
rock-pigeon, is 21/4 inches too long, and the two wings, from tip to tip,
51/4 inches too long. In disposition this bird is singularly quiet,
seldom flying or moving about, as Bechstein and Riedel have likewise
remarked in Germany.[295] The latter author also notices the length of
the wings and tail. The beak is nearly .2 of an inch shorter in
proportion to the size of the body than in the rock-pigeon; but the
internal gape of the mouth is considerably wider.

GROUP IV.

The birds of this group may be characterised by their resemblance in all
important points of structure, especially in the beak, to the rock-pigeon.
The Trumpeter forms the only well-marked race. Of the numerous other
sub-races and varieties I shall specify only a few of the most distinct,
which I have myself seen and kept alive.

RACE X.--TRUMPETER. (Trommel-Taube; Pigeon tambour; glougou.)

_A tuft of feathers at the base of the beak curling forward; feet much
feathered; voice very peculiar; size exceeding that of the rock-pigeon._

This is a well-marked breed, with a peculiar voice, wholly unlike that
of any other pigeon. The coo is rapidly repeated, and is continued for
{155} several minutes; hence their name of Trumpeters. They are also
characterised by a tuft of elongated feathers, which curls forward over
the base of the beak, and which is possessed by no other breed. Their
feet are so heavily feathered, that they almost appear like little
wings. They are larger birds than the rock-pigeon, but their beak is of
very nearly the same proportional size. Their feet are rather small.
This breed was perfectly c
