Falcons: Fast flying with long, narrow, pointed wings and quick wing beats. Possess dark brownish-black eyes and have a notch in the beak called “tomial tooth” used to severe the spine of their prey. This group also has baffles in their nostrils that prevent too much air from entering their system at one time when flying at high speeds.
