a different aggression
 
I have seen eagles chase ospreys and other eagles, trying to get their fish.
I have seen fledgling ospreys chase each other trying to get the other’s fish.
Today I watched 2 adult male ospreys, over the Haw River, below the dam, get into a chase.
I don’t know what started the chase.  
There is not an osprey nest anywhere close by the dam so I don’t think nest protection was the basis.
These two tumbled and rolled and screamed above the riprap and up and out over the dam toward the lake.
You never know what you will see at Jordan Lake!
 
 
 
 

Osprey dive at somewhere between 30-50 mph on average.
 
The dive goes like this:
 
Fish spotted and instant flight path changed from horizontal to vertical.
 
 
Picking up diving speed by becoming completely vertical.
 
 
Preparing horizontal attack path.
 
 
Plow into the water.
 
 
Climbing out of the water.
 
 
Heading home with breakfast.
 

Ospreys go in, I mean often way deep under water when fishing.
The dive picks up a lot of water on the body of the osprey.
Water weighs 8.35 pounds per gallon.
Flight calls for a bird without an excess load to haul into the air.
Ospreys do a shake to shed the excess water. The shake is just like what a wet dog does.
The shake starts at the beak and twists through to the tail.
Here you can see the osprey is ahead of the spray and the shake has gotten almost to the tail feathers.

Osprey Fish Dance in 4 Steps
 
The osprey is superb at hovering over the water, watching a fish.
 
 
The twist in midair to track the fish.
 
 
The impact into the Haw River, which is running at 10,000 cubic feet per second. 
See this morning’s FB video and realize this approximately 3 pound bird is fishing in FAST moving water.
 
 
Fish caught.  Now to make a run for the nest before the bald eagles realize the osprey has a catch.
