I find that black vultures are often a source of mystery. It isn't that they are particularly cryptic in and of themselves. It's their coloration. Since they have black feathers, a bald black head, black eyes, and a dark beak; they are effectively all silhouette. And since they often tuck their head in or hold it at odd angles, they are often fairly indistinct silhouettes at that. Often, I will spot a bird perched in a tree or on a pole with the sun at its back and start thinking of all of the possible birds that it could be, only have it turn out to be this living silhouette, the black vulture.
Sunday, as I was riding in the middle of nowhere, I spotted a large bird perched on a power pole. The sun was at its back, so all I could make out was its shape. My first thought was, "this has to be a black vulture, of course."
As I got closer, I started to have doubts. "The head just isn't right for a black vulture. Could it be a turkey vulture?"
I get closer. "Hmm. The head shape doesn't really work for either vulture. The beak looks too thick for a hawk. Crested caracara?"
I start to get a bit hopeful. Crested caracaras have been reported in the area, but I haven't seen any on this trip. They are striking birds and it would be a great opportunity, but there's a problem. "The head would work for a caracara, but that bird is huge. What could it be?"
I finally start to get parallel with the bird. The pole that it is on is now 10 yards away from me. The light has shifted enough so that I'm not just looking at a dark shape. I can now clearly make out the bright yellow beak and the pure white feathers on its head. I couldn't help but think, "Aha. American bald eagle. I guess that will have to do."
Fortunately, the bird did not hold the slow identification against me. It stayed on the pole and let me take as many pictures as I wanted. (Such as the 2 below)
