Seagull

Seagulls are common, passive mobs,

Naturally
Seagulls spawn in the beach biome or a Forest near the Beach, in light levels over 7, with at least 1 space above. there is also an 80% chance that a seagull will spawn above a 4x4 spawn with more than 3 cod, salmon, or tropical fish.

7% spawn as babies.

You can breed them with salmon for a baby seagull.

Food
Seagulls are attracted to players with food in their hand, villagers with food in their inventory, or wandering traders selling food (buckets of fish).

You may feed seagulls, which will attract more.

Nests
Seagulls live in Seagull nests and will attack zombies and drowned that go near them. They can easily defeat a zome with the advantage of flying, but as for drowned, they are not good at that.

Taming
You can tame a Seagull with a potato. It will not, unlike the parrot, sit on your shoulder, but will follow you around, flying if necessary. If you travel a considerable distance from it, it will teleport.

Tamed Seagulls are useful as they will lead the player to a wandering trader or villager who sells food. The tamed Seagull will scan the 16x16 area to look for a client. If they find one, they will squark twice and lead the player at walking speed, to a trader.

Use on them to sit.

Drops
They will drop 1-3 XP, a feather, and possibly raw salmon

Like most mobs, killing a baby seagull yields no items or experience
