This RTH apparently thought he had a mouse or a vole but it turned out he didn't have anything. I was hoping he would have caught something but the fact that the prey got away provided an interesting show of the hawk digging in and looking to make sure. Thanks for viewing this sequence!
Here the RTH pounces on the elusive prey and covers with the wing. Note the nictitating membrane is activated in case the prey fights back.
Here he's stirring his talons around, adding some lift with the wings--kicking up grass in the process, trying to locate his lunch.
Trying the stirring method again
Finally, both talons are lifted off the ground and quite a bit of ground material is tossed into the air above his head.
Shortly after this he concedes and flies off.







Wonderful series
