For some you may already know…something I find intriguing.
Coopers Hawk chicks when they hatch have yellowish eyes while the adults have reddish eyes.
Same for Osprey only reversed…young Osprey have red eyes and the adults yellow.
The eye color changes for yellow to red in Cooper’s and from red to yellow in Osprey as they become adults.
Why is this…I have no idea.
Simply some tid-bits of information from the Bird World.
