THE COCK OF THE ROCK.

The COCK OF THE ROCK (_Rupicola crocea_), the best known species of this

group, has been minutely described by many writers. The rich plumage

of the adult male is of a bright orange-yellow; the feathers that form

the crest are deep purplish red; the large wing-covers, quills, and

tail-feathers brown, edged with white at their tips, and marked with

large white spots. The females and young are of an uniform brown; the

lower wing-covers orange-red; the rump and tail-feathers light reddish

brown; and their crest considerably smaller than that of the male. All

have orange-red eyes, greyish yellow beaks, and yellowish flesh-pink

feet. The male is twelve inches long; his wing measures seven and his

tail nine inches, the female is at least two inches smaller.

The Cock of the Rock is an inhabitant of Guiana and North-eastern Brazil,

where it frequents well-watered mountain regions, and the immediate

vicinity of waterfalls, only quitting these localities about June or

July, to visit the woods and forests, in order to procure the abundant

supply of ripe fruit that awaits it at that season; but it never, even

during these excursions, descends into the open plains. Humboldt met with

these birds on the shores of the Orinoco, and Schomburghk encountered

them twice, each time in large flocks, whilst he was travelling through

British Guiana, once on the Canuku Mountains, and again amongst the

sandstone rocks near Wenham Lake. "On one occasion," says Schomburghk,

"after ascending to the summit of a lofty precipice, so entirely covered

with huge blocks of granite overgrown with moss and ferns as to be almost

impassable, we came suddenly upon a small open spot, entirely destitute

of vegetation. A signal from the Indian who accompanied me warned me to

conceal myself silently amongst the surrounding brushwood. We had only

been for a few moments thus hidden from view, when we heard a sound so

exactly resembling the cry of a kitten that I concluded we were about

to attempt the capture of some small quadruped. The cry was instantly

and most exactly imitated by my guide, and he was again answered by

similar voices proceeding from every direction. In spite of a sign from

the Indian to have my gun in readiness, the first sight of the beautiful

birds, whose strange notes had thus deceived me, took me so completely

by surprise, that I quite forgot to fire until too late; for after

darting rapidly from the bushes, and ascertaining by a rapid glance that

they had been deluded by a false cry, they instantly retreated to their

former shelter. Before leaving the spot, however, I succeeded in shooting

seven of the flock, but was not fortunate enough to see them perform the

peculiar dances and evolutions I had heard described by my brother and

my Indian guide." We will give our readers a description of the strange

and interesting spectacle here alluded to, as afterwards witnessed by

himself; in the same naturalist's own words:--"Having at last attained a

suitable spot, we listened breathlessly for the cry of the birds, and my

guides having ascertained exactly where they were amusing themselves, I

was noiselessly conducted behind some bushes close to their ball-room,

and after we had lain ourselves flat on the ground, saw one Of the most

attractive and extraordinary sights I ever beheld. Some twenty of these

glorious birds were seated upon the stones and rocks around a small open

space, in the centre of which a solitary male was dancing vigorously,

and performing a great variety of evolutions, alternately springing

repeatedly with both feet from the ground, spreading his wings, and

moving his head, with most comical gestures, from side to side, waving

his tail like a wheel through the air, and then, when nearly exhausted

by his long-sustained exertions, concluding by walking coquettishly

around the open space, as though desirous to receive the applause of the

spectators, which the females expressed by uttering a very peculiar cry.

One after another the males came down and took their turn in amusing the

company, each going back to his seat before another performer commenced.

So completely absorbed was I in watching these strange evolutions, that I

had entirely forgotten my Indian companions, and was much startled when a

sudden shot was heard, and four of these beautiful birds fell. The rest

of the party at once rose in great terror, leaving their companions dead

upon the ground."

The remarkable performance thus described by Schomburghk is no doubt a

part of the courtship of the Cock of the Rock. We learn from the same

authority that the nestlings are to be found at all seasons of the year,

but in the greatest numbers about March, when the plumage of the male is

in its full beauty. The nests found by Humboldt in Orinoco were made in

holes in the granite rocks, whilst those seen by Schomburghk were built

in clefts and fissures, suspended like the nest of a Swallow, and covered

with resin. One of these nests is often occupied for years together,

and repaired by the addition of fresh fibres, feathers, or down, for

the reception of each new brood. It is by no means uncommon to find a

great number of nests in the same cleft or hole. The brood consists of

two white eggs, marked with black, and somewhat larger than those of a

Pigeon. The nestlings are reared upon the same fruits and berries that

afford the parents their principal means of subsistence. Great numbers of

these splendid birds are shot annually, as their skins not only command a

high price, but are much employed by the Indians in making a variety of

beautiful decorations: a large state mantle worn by the Emperor of Brazil

was entirely composed of their feathers. In some districts of South

America the natives are compelled to bring a certain supply of skins as

tribute, and are thus quickly diminishing the numbers of these elegant

creatures. Their flesh is well-flavoured, but of a very peculiar colour,

being bright orange-red. Humboldt tells us that the Cock of the Rock is

much valued by the Indians as a domestic favourite, and is kept by them

in cages made of the stalks of palm-leaves.

Another very similar species, found only in Peru, the Peruvian Cock of

the Rock (_Rupicola Peruana_), lives entirely amongst trees, upon the

berries and fruits of which it subsists; but it exhibits none of the

dancing propensities of its Brazilian relative. We learn from Tschudi

that in no instance did he ever see one of these Peruvian birds either

on rocks or upon the ground, but always associated in large flocks, that

lived and built their nests upon trees. He tells us that they are easily

discovered from a considerable distance by their loud and most discordant

cry.

The TRUE MANAKINS (_Pipra_) comprise a number of small and most

magnificently-tinted birds, distinguished by the shortness of their wings

and tails. In the former the primary quills are graduated, very narrow

towards the tip, and do not extend beyond the base of the small tail,

which is either conical or quite straight at its extremity. The short

high beak is compressed at its centre, slightly incised directly behind

the hook that terminates the upper mandible, and furnished with a sharp

ridge at its culmen. The tarsi are high and thin, and the toes short,

the outer and centre toes being united as far as the first joint. The

compact thick plumage is extremely short in the region of the forehead,

and takes the form of fine bristles around the nostrils and the base of

the beak. In the coloration of the male, black predominates, affording

a rich contrast to the glowing fiery tints that adorn some parts of

his body; whilst the females and young usually appear in a modest garb

of greyish green. The Manakins live in pairs, or small parties, and

principally frequent the inmost glades of their native woods and forests,

hopping from bough to bough with untiring sprightliness, and enlivening

the most gloomy recesses of their sylvan haunts by their gay colours and

animated twitter. Before noon these pairs or parties unite with other

birds in search of food, and at the approach of the mid-day heat again

retire to their favourite sheltered nooks. Insects, fruits, and berries

of various kinds, constitute their principal food, and to obtain these

they occasionally venture near the abode of man. Schomburghk mentions

having seen several of these usually very timid birds approach his tent

daily, in order to gather the ripe fruit from some fig-trees that grew

close to his encampment. The nest of the Manakins is carelessly formed of

moss, and lined with cotton wool. The two eggs that constitute a brood

are unusually elongated, of a pale tint, and marked with delicate spots

that generally form a wreath at the broad end.

The LONG-TAILED MANAKINS (_Chiroxiphia_) constitute a prominent group of

the family under consideration, and are recognisable by the prolongation

of the centre tail-feathers, this peculiarity being particularly

observable in the male.
