We love these guys. They seem to tolerate us here at the marina. Barely. They are the curmudgeons of the avian world.
If one happens to be standing (they're not small - waist to chest high, depending on how much of that neck is extended) on the dock when you are coming, they will sloowly stalk out onto a finger pier, while giving you the evil eye for disturbing their royal presence.
And when they can tolerate you no more, they will produce a sound that can only be described as "Gronnk!", spread their gymongous wings, flap once, and glide in ground effect over to another dock. When you hear that sound, you will have no doubt that dinosaurs are alive and well in our modern world. But now with feathers.
And, if you are a thinking person, you are grateful that they are not Jurassic-sized, for surely then you would be dinner.
