The ROCK MANAKIN 
Has an erc£l crefl, with a purple margin. The plumage 
is of a fdHYon colour, and the coverts of the tail are fquarc, 
as though cut off. 
This bird is the ftze of a fmall pigeon, and 
very beautiful ; the plumage, though of one co¬ 
lour, being very regularly difpofed. When 
young, its feathers are brown, afterwards of a 
ruff colour ; it is only by degrees that it acquires 
that beautilul orange, which diffinguifhes this bird 
in its more advanced age. 
It is an inhabitant of South America, and is 
found in various parts of Surinam, Cayenne, and 
Guiana, in rocky fituations ; but no where fo 
frequent as in the Mountain Luca, near the 
River Oyapoe, and the Mountain Courouaye, 
near tlve River Aprouack : they build therein 
deep chafms of the rock, and in large caverns 
and recedes, where the lun never penetrates. 
I heir neffs are of a very coarfe conffrudfion, 
made like that of the wild pigeon, principally of 
dry flicks. 
It is probable fince they are fo fond of an 
obfeure retreat, that their eyes are capable of 
confiderable contraction, and dilatation, like thole 
of the owl, becaufe they are feen in the day, par¬ 
ticularly
