Watch this osprey get fully submerged.
I find it amazing that the bird has enough energy to take off as water-laden as it got.
Note the “rounded” wing flap necessary for enough lift to fully emerge and propel itself from the surface carrying not only the fish but a few pounds of water caught up in its feather (integumentary) system.
Towards the end of the video, watch the bird begin to straighten out the fish as it climbs higher to make it (the fish) more aerodynamic.
Birds have no muscles in their legs from thighs down.
There are 2 (flexor) tendons in each leg that act as an eloquent pulley system.
The foot closes as the ankle angle changes.
This is why birds can sleep on one foot, the tendons lock.
Since there are no muscles, the feet and legs never get “tired.”

A wiggling fish will slow things down and the bird is looking forward to eating sooner rather than later.
Predatory birds like this osprey use the tendon system to kill its prey by closing their huge talons into the fish’s body – “wiggle be gone”.

As a counterpoint to this:
Unless you have been training your bird for free flight daily chances are the muscles driving its wings don’t have near the horsepower of an Osprey.
If you should have the unfortunate circumstance of your bird escaping and landing on the tree in front of your home, a prescribed method of recovery is to spray it with a garden hose.
A saturated cockatiel can barely fly and will not gain altitude when saturated.
