At our place up in Tomahawk, WI, we have Bald Eagles that regularly visit the large pine tree right outside our front door. Often we'll hear crows loudly yelling at the Bald Eagles perched there, and then the distinct chilling screech of the Eagle right before they leave to prey on some animal below them on the food chain (pretty much anything).

In this shot, the eagle just leapt off the branch before quickly heading to the lake, looking for a fish dinner.
