The large mushroom on Parakrow's head produces spores that attract other Pokémon infested by the same fungus. If Parakrow lands in a tree, this crowd of other Pokémon will gather around and quickly devour it.
Becoming active at night, it is known to swarm with numerous Murkrow in tow. Parakrow are known to infest the roots of large trees en masse and drain nutrients.
