The 174th prohibition is that we are forbidden from eating a non-kosher bird.
The source of this prohibition is G‑d's statement regarding those species,1 "These are the flying animals that you must avoid. Do not eat [the following:]. "
One who eats a kezayis of their meat also receives lashes.
The details of this mitzvah — along with the previous two2 — are explained in the third chapter of Chullin.3
