wiktionary
From crow(“crow (bird)" also "metal lever, crowbar”) + bar, probably because the forked end looks like a crow's foot.
etymonline
crowbar (n.)
also crow-bar, "bar of iron with a wedge-shaped end," 1748, with bar (n.1), earlier simply crow (c. 1400); so called from its "beak" or from resemblance to a crow's foot; or possibly it is from crows, from Old French cros, plural of croc "hook."
