164. Circus macrurus. Pallid Harrier. 
Circus macrurus (S. G. Gm.), 
Iris brown ; bill black ; legs yellow. 
The Pallid Harrier was not infrequently seen hawking

165. Circus cineraceus. Montagu’s Harrier. 
Circus cineraceus Cuv. 
Iris hazel; bill black; legs yellow.

Iris yellow ; feet light yellow.
