The prowbeak was found along the Thuringian shores of the shallow European epicontental sea that occurs along the western edge of the shrinking Thethys. Many varieties existed of prowbeaks, but among them, the especially toothsome white-headed prowbeak was the most numerous. Prolific, forming massive lekking colonies, white-heads are the most social amongst prowbeaks, but are also notorious raiders, and have been known to steal food from more adept hunting species such as the distantly related Dentate Heron-Jaw, Pterodactylus. Prowbeaks have very long, stiffened tails, crowned at the end with a broad flag-like vexillum, which is often colored bright shades without much ornamentation, but are highly visible. Dancing for mates is a common scene as males develop their leks -- or try to steal from other males' leks -- and involves vigorous dashes about a small area, tail held high, displaying the prowess and health of the dancer. During this time, the male consumes ample soft-shelled animals which pigments its facial skin and beak a bright pinkish red, and consequently the head is also turn pink.

If a diver, it makes sense. This isn't intended to be a formal argument. I am still working on some data to speculate on its diet, and I wanted to think about flamingoes and other animals that consume shoal or near-shore foods. Who knows what this thing ate!
Nice work here! I very much like how you incorporated the possible behavior and a common name. It's rare to see that in many depictions of prehistoric life, but it's always a treat to see what ideas people may have regarding that.
