I happened across this scene yesterday and while a bit graphic, found it fascinating.
When I first arrived, the rabbit’s foot (apparently not so lucky) was out of view and I thought perhaps it caught a snake. On closer inspection though the skull was visible and then the hawk rearranged its catch and the foot could be seen.
I don’t believe this hawk devoured the entire rabbit though as that would be a lot for this size of raptor but rather probably was picking at what was left of another hawk or eagle’s meal. There were in fact two other hawks circling the scene keeping close watch.
