Leafwing

The Leafwing is a species of avian reptile monster that first appeared in the Legendary Pictures films Kong: Skull Island, and reappears in the film's tie-in comic Skull Island: The Birth of Kong. The creatures are also featured very briefly in the next two entries in the MonsterVerse, Godzilla: King of the Monsters and Godzilla vs. Kong.

Personality
While less aggressive than their Psychovulture cousins, the Leafwings are still dangerous airborne predators. They are omnivorous.

Kong: Skull Island
The Monarch expedition to Skull Island encountered Leafwings on three occasions. While Preston Packard and several soldiers were looking for Chapman, they spotted a tree with dozens of Leafwings perched on its branches. Packard took aim at one of the creatures with the scope on his M14 rifle, shooting it in the head and scaring away the others.

James Conrad's group was beset by several Leafwings while traveling by river on the Grey Fox. Conrad and Slivko were unable to get a clean shot at the birds as they carried off Nieves, and the group could only watch as he was dismembered and devoured in mid-air.

Leafwings disturbed by the battle between a Skullcrawler and the remaining members of the expedition attacked the latter, killing several soldiers. Conrad sliced several of them in half with Hank Marlow's katana while rescuing Slivko.

Godzilla: King of the Monsters
Several Leafwings flew around Godzilla moments after he killed King Ghidorah in Boston, having emerged from the Hollow Earth after Ghidorah's cries awakened all of the Titans around the world.

Godzilla vs. Kong
After the perpetual storm surrounding Skull Island consumed it, multiple Leafwings lived within the domed habitat Monarch built for Kong. They lived peacefully alongside the discontent Titan. The joint Monarch-Apex Cybernetics expedition to the Hollow Earth discovered more Leafwings shortly after entering the realm.
