The smallest of the large monsters, Bird Wyverns come in two different flavors, alpha, bipedal, flightless wyverns, and miniature versions of Flying Wyverns. Alpha Bird Wyverns are reminiscent of dinosaurs, and are very social creatures, commanding a pack of nondominent smaller versions of themselves and using them to attack as often as they do. The other flavor of Bird Wyverns are more solitary, aggressive, and dangerous, and are great as practice before tackling a true Flying Wyvern. Don’t not take them seriously though.
