These are Glossy Ibis. They are east coast birds. This is way I see them flying through the front yard. They do fly by quite fast! I usually have less than five seconds to get the camera up to my face and get a shot.
While I was visiting the Salton Sea, I managed to stumble upon a flock of White-faced Ibis. This is a west coast bird.
I was even lucky enough to get this juvenile.
