    John, Fabs suggested I post this eye from the Owl I posted earlier in the Avian Forum. Something seems amiss with the eye. Thanks, John

    Is that from the pair behind the baseball field? I was there in February and noticed they had those "marble" eyes instead of the yellow ones. Don't know the reason, but looks cool IMO.

    Was it a young bird? Check out Sibley's "Florida Fledgling" (Feb-Sep)... it shows a funky dark eye pattern, so thats my guess

    I don't know what is causing this effect in the eye, but here is another burrowing owl image that I posted in the Avian forum about a year ago. If anyone has an explanation, I too would like to hear it. (This was an adult bird paired with a normal-looking owl.)

    Really interesting. Artie has just posted a similar looking bird (eyes that is) in his latest bulletin.

    When I have human patients with this effect we call them iris freckles. It is just more pigment showing through in spots. Pretty much normal in humans - I don't know about owls.

    Athene cunicularia floridana is the subspecies of Burrowing Owls found in Florida and the Bahamas... the best I can find states "Yellow eyes (irises) are most common; but chocolate or olive irises have been documented." So I am going to assume this is just a rare trait that occurs in this subspecies, maybe just a different 'morph.'
