Crows

A bird mob spawns in taiga and lives in groups, they are larger than parrots and have 2 behaviours:

1. sometimes they surround the fox and scare him and maybe attack him a bit(we don’t want to kill foxes gradually) or they surround the player, they are not hostile but kind of bully and when one of them is attacked all of them will attack back, since they fly there will be less barriers for them to reach their target and it is hard to trick or avoid them.
2. They like walnuts, a huge tree I’ve mentioned in previous suggestion grows in taiga, and crows will help farm this tree picking its fruits.
