Harris Hawk in Black and White

Last week I wrote this post about a photo I took of a Harris Hawk.  I asked for some feedback; thanks to all of you that wrote a comment.  One of them was a suggestion that I post process in black and white.  It just so happens that I was back to see the hawk a few days after I had taken the original photo, and I actually took it in black and white.  Here is what I consider the best of that series:

ISO 160 50mm f/3.5 1/40

I’m just not crazy about it, because of the lack of detail in the face.  Here is the picture from the first post, just so you can see them near one another:

ISO 125 50mm f/5 1/25

Thoughts?

Cheers!
