Friends, these redtails represent the various types of redtails in the air, being released after banding, the left image shows an immature male with lots of white showing, the right top shows a mature female with two feathers growing back into her tail, she must have run into a tough challenge and lost part of her tail, good thing that feathers regenerate fairly quickly.  The bottom right image is the rufous redtail with very little white showing on his underside.  Click on the image and follow the arrows for a full-sized slideshow. til Tomorrow MJ
