Apparently, there are more than a few of these unusually-coiffed birds around. Over the years, I've photographed two individuals at Marina Park in Kirkland, Washington, never realizing (as they were two-years apart AND i never really checked) I'd photographed two individuals.
For someone as visually-oriented as myself, consider this a wake-up.
Anyway, this morning I'm pawing through a friend's website when I come across a photo that reminds me of my two little darlings, and I thinks to myself, "Hey, Stupid, there are more of these things out there!".
And, so I wander into my archives and lo, one is male, the other is female, separated by two years.
Any biologists care to take a potshot into why this particular mutation occurs, and just how prevalent it is?
