This proudly plumed Cormorant was looking for some attention, or at least some other Cormorant attention (it didn't hang around me for very long). When one is a lonely Cormorant and is looking for companionship, the best and most time-tested method for finding a mate is to grow spindly white plumes on the back and sides of one's head.
This makes one look distinguished, wise, and spunky--the perfect candidate for a pater familias. It might be a widely believed fact that the European gentlemen of the late 1700s used the Double Crested Cormorant as an inspiration for their powdered wigs.
