   lacking the prominent tooth and notch of the bill, and in
   having shorter and less pointed wings. Many are of large size
   and grade into the eagles. Some, as the goshawk, were

   word is not infrequently applied, also, to true falcons, as
   the sparrow hawk, pigeon hawk, duck hawk, and prairie hawk.

Easton's 1897 Bible Dictionary:

Hawk
   (Heb. netz, a word expressive of strong and rapid flight, and
   hence appropriate to the hawk). It is an unclean bird (Lev.
   11:16; Deut. 14:15). It is common in Syria and surrounding
   countries. The Hebrew word includes various species of
   Falconidae, with special reference perhaps to the kestrel (Falco
   tinnunculus), the hobby (Hypotriorchis subbuteo), and the lesser
   kestrel (Tin, Cenchris). The kestrel remains all the year in
   Palestine, but some ten or twelve other species are all migrants
   from the south. Of those summer visitors to Palestine special
   mention may be made of the Falco sacer and the Falco lanarius.
