THE ROLLER.

Coracias Garrula, LINNÆUS; Le Rollier d'Europe, BUFFON; Die

Mandelkrähe, BECHSTEIN.

This bird resembles the jay in size and form, and is twelve inches in

length, of which the tail measures four and a half; the beak is

blackish, before and behind the eyes is a blackish triangular spot,

formed by the naked skin; the iris of the eye is grey; the whole of the

head, the neck, the throat, the breast, the belly, the large

wing-coverts, and all the under-coverts, are of a beautiful bluish

green; the tail is of a dusky blue green near the base, becoming

gradually lighter towards the end.

The female and young ones of the first year have the head, neck, breast,

and belly of a reddish grey tinged with bluish green; the back and the

last quill-feathers are of a light greyish brown; the rump is green,

tinged with indigo; the tail blackish with a tint of blue green; the

rest like the male.

HABITATION.--In its wild state the roller may be found in Europe and

the northern parts of Africa; it only frequents a few spots in

Germany, and prefers forests and sandy plains to high mountains:

elsewhere it is only seen during the time of its passage[19].

In the house it may be let range at will after the wings are clipt.

FOOD.--When wild, its principal food is insects and worms; it also

eats small frogs, bulbous roots, acorns, and grains of corn.

BREEDING.---The nest, placed in the hole of a tree, is made of small

twigs, hay, feathers, and bristles. It lays from four to seven white

eggs, on which the male takes his turn to sit during eighteen or

twenty days. The young ones do not acquire their fine colours till

the second year; previous to this period the head, neck, and breast

are of a whitish grey.

I had till lately thought that this bird was untamable; but Dr. Meyer

of Offenbach has convinced me to the contrary, having himself reared

them several times, and kept them in his room. This is his method:

The young ones must be taken from the nest when only half grown, and

fed on little bits of cow's heart, or any other meat which is lean

and tender, till they can eat alone; small frogs, worms, and insects

may then be added. The means which it takes to kill and swallow these

insects are curious enough; it begins by seizing and crushing them

with its beak, and then throws them into the air several times, in

order to receive them in its throat, which is very capacious. When

the piece is too large, or the insect still alive, it strikes it hard

against the ground, and begins again to throw it in the air, till

falling not across, but so as to thread the throat, it may be easily

swallowed.

After having been fed thus long enough, a little barley-meal may be

mixed with the meat. I have even brought it to eat bread, vegetables,

and softened oatmeal, but it always prefers cow's heart. I have never

seen it drink.

It knows the person who takes care of it, comes at his call to eat

from his hands, without however letting itself be caught: but it

never becomes quite tame, and often defends itself with its beak. It

makes very few movements unless to seek its food, and generally

remains quite still in the same place. If it ever hops about the room

it is in an awkward and cramped manner, on account of its short feet;

on the other hand, it flies very well; but it must not be left

completely at liberty in the room, or quite shut up in the cage,

because it is so easily startled, and in its fright gives itself such

violent blows on the head as would soon kill it. The best way is to

clip one wing, and then let it range the room. These birds quarrel

with one another, particularly in the evening, for their places on

the perch. I have kept them for some time in a large aviary with

small and great birds, and once with my pigeons which I kept shut up;

generally I have them in my room, where they mix with several other

birds: but whether alone or with companions they appeared equally

healthy and active.

ATTRACTIVE QUALITIES.--They have few other attractions besides their

beautiful plumage, for their voice is only a harsh croaking "_crag,

crag, craag_[20]."
