CORA'CIAS,y. the Roller; in ornithology, a ge¬ 
nus of birds belonging to the order of picae ; of which 
there are twenty-five lpecies now known. The generic 
characters are : bill knife-fhaped, curved at the tip, bare 
of feathers at the bafe ; tongue cartilaginous and bifid ; 
feet ambulatory. This tribe is nearly related to the 
crows, and hence Tiled by Linnjeus, coracias, a word ap¬ 
plied by AriEotle to what is now known by the name of 
the chough, or Cornidi crow. Gefner lays the German 
name roller, was expreflive of its cry ; Schwenckfeld fays 
the fame of rache. One of them muE be deceived, and 
it is probably Gefner; for the name rache, adopted by 
Schwenckfeld, is more analogous with thofe given to 
this bird in different countries, which are derived from 
its cry. In German, galgcn-regel, halk-regel, gals-kregel, 
racher ; in Polifh, krajka ; in S-wedU\'t,Jpa/Jh-kraJka. It 
has alio the following names in Germany : Kcidcn-eljlcr, 
kugel-eljlcr, viandcl-krac, dcutfchcr-papagcy, birk-heber, i. e. 
he.ith-magpie, ball-magpie, almond-crow, German po¬ 
pinjay, birch-jay. The following are the fpecies afeer- 
tained by Gmelin: 
1. Coracias garrula, the common roller; the general 
plumage of which is blue ; back red; quill feathers 
black. It has a kind of wart behind the eye, and the 
eye itfelfis furrounded with a ring of yellow naked (kin. 
It is a bird of paffage, and performs its migrations re¬ 
gularly once a-year, in the months of May and Sep¬ 
tember. It is found in Sweden and in Africa; but we 
muE not fuppofe it fettled in the intermediate regions. 
It is unknown in many parts of Germany, France, and 
Swifferland. We may therefore conclude, that, in its 
paffage., it moves only in a narrow zone from Smaland 
and Scania to Africa. There are points given to mark 
nearly its trad! through Saxony, Franconia, Suabia, Ba¬ 
varia, Tirol, Italy, Sicily, and the ifiand of Malta, which 
is a fort of general rendezvous for all the birds'that crofs 
the Mediterranean. The one deferibed by Edwards, and 
Eiewn in the annexed engraving, was killed on the rock 
of Gibraltar, whence it could wing its lofty courfe to 
the African lhore. It is feen fometimes in the vicinity 
of Strafburg, and even in Lorraine, and in the heart of 
France ; but thefe are probably young ones, which Eray 
from the main body. 
The roller is more wild than the jay or the magpie : 
it fettles in the thickeE and the moE folitary woods; 
nor has it ever been tamed or taught to fpeak. Its plu¬ 
mage is beautiful ; it has an alfemblage of the fineE 
ihades of blue and green, mixed with white, and heigh¬ 
tened by the contraE of du(ky colours. The young do 
not affume the delicate azure till the fecond year ; whereas 
jays are decorated with their moE beautiful feathers be¬ 
fore they leave the neE. The rollers build, when it is 
in their power, on birches; and it is only when they cannot 
find thefe that they make ufe of other trees. But in coun¬ 
tries where wood is fcarce, as in the ifland of Malta, and 
in Come parts of Africa, they form their neEs on the 
ground. Thefe birds are often feen in company with the 
COR 
wood-peckers and crows, in the tilled grounds near the 
foreEs. They pick up the final 1 feeds, roots, and worm , 
which the plough throws to the furface, and alfo the grain 
that is lately (own. When this fupply fails them, "they 
have recourfe to caterpillars, grafiioppers, flies, and frogs.' 
Schwenckfeld adds, that they fometimes devour carrion; 
but this muE be during winter, and only in cafes of ab- 
folute want; for they are in general regarded as not car¬ 
nivorous, and Schwenckfeld himfelf remarks that they 
are very fat in autumn, and then are good eating, which 
can hardly be faid of birds that feed on flefh. 
Aldrovandus, who feemsto have been well acquainted 
with thefe birds, and who lived in a country which they 
inhabit, a Herts that the female differs much from the 
male, its bill being thicker, aud its head, neck, breaE, 
and belly, of a chefnut colour, bordering on afli-grey, 
while the correfponding parts in the male are of the co¬ 
lour of the beryl, with different reflections of a duller 
green. It is very probable that the two long outfide 
quills of the tail, and the warts behind the eyes, which 
appear only in fome individuals, are the attributes of tire 
male, as the fpur is in the gallinaceous tribes, and the 
long tail in the peacocks, &c.
