Could my Wyverns exist?

A long time ago, Yi Qi diverged into three main groups: Cockatrices, Drakes, and Wyverns. Some characteristics of Wyverns include:

• They are tetrapods/quadrupeds
• They are covered with feathers
• They have horns
• They have bat like wings
• They are roughly the size of quetzalcoatlus (some are slightly larger)
• The males gather shiny objects in their nests to attract mates
• They have small tails
• They are carnivorous
• They can support the weight of ONE unarmored human
• They store a flammable liquid in a gland of some kind, which they then ignite and release onto their victims

Given these characteristics, could such a beast realistically exist?

NOTE: Magic does not exist in my story
