Hashs's Falcons adds the titular falcons, tameable neutral mobs that spawn in various biomes. There are two color variants, a brown variant and a grey variant, which spawn in different sets of biomes.

In the wild, falcons will hunt farm animals periodically, diving down from the sky. They won't hunt farm animals near players, villagers, or armor stands. They'll also retaliate if attacked. Feed them rabbit stew, however, and they will cease their predatory behavior and instead follow you from above, attacking anything that attacks you! Rabbit stew can also be used to heal an injured falcon.
