When people think of photographing birds, the more exotic types are going to probably be of more interest to many.  While I am obviously (if you follow this blog) partial to photographing an eagle or an owl, I also find the more common birds cool.  A pigeon has some amazing flying capabilities, gulls can look elegant in flight and crows have fantastic feather coloration.  One of them was sitting on a fence very close to me as I sat in the car.  The light was glinting off the feathers making the subtle colors show up nicely.  How could I not photograph it?  You might dismiss the average crow, but they can look very cool.
