The Osprey is a difficult raptor to rehab, they just are not meant to stand on the ground. They are built for flying (long narrow wings), diving into the water for fish with long outstretched legs and sharp talons, and then perching on branches to feed and rest.
On the ground they are extremely clumsy and if the rehabber is not careful the bird will literally break every tail feather as well as all of its primary wing feathers (those out on the tips of the wing).
Without these essential flight feathers, they are doomed and regrowing them and not REbreaking them is a process we've had to do on occasion and it just extends the care period out (requiring special permission for the federal government) from a few weeks to up to a year, depending on the time of year they arrive.
This was a very good release and makes a rehabber extremely pleased.
After rehabilitation for a broken coracoid (collar bone) caused by a vehicle collision, "Aquila" the male Bald Eagle is successfully released over Willard Bay, Utah.
