Hawk, powerful, sharp beak for catching prey. 



Woodpecker, chisel edged, for chipping wood. 



Whip-poor-will, weak beak but wide mouth, surrounded by stiff hairs, for

Snipe, slender and sensitive, for probing after food in the mud along the 

 shore.

The optic lobes are also well developed but the olfactory (smell) 

 lobes are usually small and the sense of taste is poor, since the food is 

 swallowed without remaining in the mouth to be chewed and tasted.
