Vulture

Vultures are large, winged predators, and one of the most persistent threats in Rain World. They move through the air using thin wings and gas propelled through their bodies, and catch their prey with a lunging bite before flying off back into the sky. Their chief disadvantage is their large size: vultures are not encountered in areas inaccessible from the sky and are unable to traverse pipes or tunnels.

Vultures are menacing foes which can appear in the majority of the game's regions. They will remain a threat throughout Industrial Complex, Garbage Wastes, Shoreline, Chimney Canopy, Sky Islands, and Farm Arrays.

Strategy
Vultures can be avoided by looking for the shadow they cast. Hiding in tunnels or small spaces may sometimes work, however, despite their size they can squeeze into surprisingly small areas and can reach into holes to pluck prey out of hiding places. Also, if necessary, Vultures can use their wings in order to traverse across the ground, though at a very slow pace.

Vultures may run away if hit by too many spears, although the amount can vary. Explosive spears can also be used to stun the vultures, allowing escaping or attacking. Vultures can be killed if enough spears are used or are lured into running into a Pole Plant, a Monster Water Kelp, Scavengers and even a Green Lizard.

The mask the vulture is wearing can be stolen or removed. However, the vulture the mask is stolen from will become exceedingly aggressive, hunting down slugcat and refusing to leave. Because of this, it is suggested to kill a vulture before taking its mask. Unmasked vultures will be 'bullied' by, and sometimes killed by, vultures with masks.

Vultures will scare nearby Lizards into hiding with the exception of the green ones. Lizards which fail to hide may be grabbed and killed. Saving a lizard from a vulture counts towards befriending the lizard. Conversely, the vulture's mask can be held and worn, and used to scare away lizards. It can also be traded to scavengers.

Surprisingly, it is possible to tame a vulture by feeding it suitable prey. The vulture will then no longer attack slugcat.

Trivia

 * The grey caps on their back open when gas is released.
 * suitable food to give to the vultures, and in turn have them leave you alone, are: centipedes (not sure about all sizes), lizards (any) and dead scavengers. But squidfrogs are still being tested.
 * giving back their mask wont have them to leave you alone.
