the male is a much smaller 
bird than the female, and is 
also more brightly coloured. 
The GOS-HAWK was at one 
time used in falconry; it is 
a bird of extremely ferocious 
disposition, and in the days 
when hawks were used for 
sporting purposes had to be 
kept very safely tethered, as, 
if it gained its liberty, it 
would at once proceed to kill 
every other hawk and falcon 
in the ‘“ mews.” 
The Falcon Tribe is 
divisible into two sections — 
the one containing the Ameri- 
can CARRION-HAWKS, and 
the other the FALCONS. 
The CARRION-HAWKS, or 
CARACARAS, are long-legged 
birds which spend most of 
their time on the ground and 
run well. They are said to 
hunt, not seldom in packs, 
after the fashion of wild dogs. 
One species at least affords an 
admirable example of mim- 
icry—so rare among birds.
