Red Tail Hawk wets its feet

In the past week I have had three interesting observations of red tail hawks.  

Last week one swooped over a cat - sized up the cat (too big) - and landed back on a low tree limb.  

Two days ago I watched another hawk swoop across a wetland - and this time it was a duck which was the target.   The duck turned upside down in the water and shook its feet in the air to avoid the hawk.

Then yesterday I was able to get within 25 feet of this wading hawk - which was hunting in conjunction with another red tail in a nearby tree.  

These birds were almost annihilated by DDT.  Check out that red tail!  Is this animal handsome! or What!
