Shearwig
Himeagea volaris
Shearwigs are enemies in both Pikmin games. They are male resembling orange winged, green Sheargrubs. They are slightly more aggresive than the Male Sheargrub, and when you take their health to the yellow zone, they take off and fly. You then need to throw Pikmin to kill them, and they also they regain health while flying. The Shearwig is never near a bridge to deconstruct it, so don't bother thinking this does the same as its cousins.
Shearwigs are not seen very often, a good place on land to find them is near the landing site of the Perplexing Pool.
