( 18 ) Accipitres. [DiuriioB.) 
Birds of Prey, They have the head and neck corered with 
feathers their eyebrows form a projection which makes the eye 
appear sunk in, and gives a character to their physiognomy very 
difleront to that of the \'ultures. The greater part feed on Hving 
prey, hot they differ much amongst themselves with respect to 
the courage they evince in pursuing it. Their first plumage is 
often differently coloured to that of the adults; they only assume 
the latter in their third or fourth year, which has caused the 
species to be much multiplied by naturalists. The female is 
generally a third larger than the male, for which reason the latter 
is called Tiercelet. (i)
