Shelter Osprey Nest
In most raptors, the female bird is larger than the male.
This is easy to see in the ospreys and bald eagles at Jordan Lake.
You can certainly see the size difference in the parents of the Shelter Nest.
Osprey Mom, heading to the left, is much bigger than Osprey Dad who is looking to the right.
Sometimes this size difference makes the female ospreys and bald eagles 25 – 30% bigger than the males.
This trait is known as gender dimorphism.
