Here are pictures of the three birds... You can click on the picture to see a larger version (and then use Back button to return to the previous page).
This is the first one I got pictures of. As you can see, she has white tips on her tail, with distinct dark bands next to the white. In this picture you can see her left leg, and she is not banded. We'll call her White Tips.
This is the next one to show up. She has no white tips on her tail, and she has distinctly rufous coloring to the feathers on her back, especially toward the tail. We'll call her Red Tail.
And this one....this is the one with the band! I looked back at my pics and I actually had a pic of her on Oct 7, but I didn't notice til today that she has the band on her left leg. Also, because of timestamps, I am fairly positive that she is a different bird than Red Tail -- her back and tail are much more blue green -- no distinct rufous coloring.
