from Easton's 1897 Bible Dictionary

Night-hawk
(Heb. tahmas) occurs only in the list of unclean birds (Lev.
11:16; Deut. 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."
