That's a great video. On the third fish, notice how it worked at shifting it's grip to carry it in a more aerodynamic fore/aft position ... not unusual.
MN and western WI BPLers might enjoy The Raptor Center's spring public release event:
11:00am - 2:00pm, Saturday May 5
Hyland Lake Park Reserve, 10145 Bush Lake Road, Bloomington, MN
In addition to releasing whatever patients that are ready to return to the wild there will be falcons, owls, hawks and bald eagles to be seen up close and personal.
Look for me if you come.
