Question: what is the difference between a hawk and a kestrel?
Answer: Buteos are the large, broad-winged, short-tailed lugs with spare and labored wing beats. Accipiters are small, narrow-tailed forest dwellers with short, rapid, bursting flaps, punctuated by a glide. Falcons are slender- and pointy-winged speedsters with steadier wing flaps.
