The following is the results of your search for night-hawk.
Night-hawk: (Heb. tahmas) occurs only in the list of unclean birds
(Leviticus 11:16)
(Deuteronomy 14:15) This was supposed to be the night-jar (Caprimulgus),
allied to the swifts. The Hebrew word is derived from a root meaning
"to scratch or tear the face," and may be best rendered, in accordance
with the ancient versions, "an owl" (Strix flammea). The Revised
Version renders "night-hawk."
