THIRTEENTH ROOM. 
The upright glazed Cases round the room contain 
the general collection of Birds. 
Cases I to 16 contain the Raptorial or Birds of 
Prey, the Accipitres of Linnaeus, which constitute the 
first Order. They are characterized by strong feet 
with sharp claws, and a powerful bill, the latter co¬ 
vered at the base by a naked skin, or cere ; their sto¬ 
mach is almost entirely membranous, and sternum broad, 
giving attachment to the muscles of their long wings. 
Some of them feed chiefly by day; their eyes are 
placed on the side of their head, and the nostrils ex¬ 
posed, as in the family of Condors, (Cases 1 and 2,) 
found principally in America, which have naked heads 
and longitudinal nostrils ; as the Condor, or Great Vul¬ 
ture of the Andes; the Californian Vulture, presented 
by Archibald Menssies , Esq.; the Turkey Buzzard of 
North America ; and the Monk and Common Neophron 
from Africa. 
The family of Vultures (Cases 3 to 5) have naked 
heads like the former, but their nostrils are perpendi¬ 
cular ; as the Pondicherry Vulture, Egyptian Vulture, 
Fulvous Vulture, White backed Vulture, and the An¬ 
gola Vulture ; these are all from the warm parts of the 
Old World. 
The family of Falcons (Cases 6 to 18) have their 
heads
