When Rough-legged Hawks dive on prey they can appear to hit the ground so hard they vicariously rattle my teeth and I almost expect them to bounce on impact.
Voles are by far the most common prey item I see American Kestrels with but occasionally I find them with a mouse or a small bird. This time, on a cold and snowy morning at Farmington Bay WMA, it was a mouse and it was still very much alive.
The transformation of Bald Eagles from juveniles to adults typically takes five years. The process is gradual but when you compare the juveniles (1st winter) to the adults and skip all the intermediate subadult stages the differences between them are dramatic.
