Comparison

I don't have much new to show, but I thought I'd put up a comparison post. A lot of these pictures are repeats but I separated them by genus and labeled them by age and sex if I knew it. We still haven't caught some varieties (like an adult male harrier) and I'm missing pictures of a few (like a female kestrel), but I thought this would give a good look at the hawks we have been catching, with side-by-side comparisons to show some differences.
