I haven't yet melleed a bird but I have caught one in air with my bow once. I've also gotten pretty decent at hitting frightened deer that are running away with my bow and I've even managed chasing some down and hitting them with melee weapons.

I know that mobs aren't supposed to spawn in areas that have work bench coverage but I have one spot inside my (rather huge) main base that a single deer insists on respawning into on occasion.

I have tame wolves in that base and would occasionally find deer meat and hides just laying on the ground when I was going to farm turnips or onions. I didn't think much of it at all. (My wife also plays and is perfectly capable of trolling me by just leaving meat and hide on the ground and then giggling when I find it). Much to my surprise I finally saw a deer just after it spawned inside the base and realized that I had a fun and re-occurring bug.
