Northern Saw-Whet Owl

Aegolius acadicus

Description:

I saw this little guy at the Toronto Zoo. I thought it was interesting how his eyes are different colors, it seems to have Heterochromia Indium which is due to an alteration in of the genes that controls eye color. Sometimes a medical condition known as Waardenberg Syndrome could also cause such a difference.

Yellow part is shown of Eye is focusing somewhere. Entire Black Eye means not focusing.

The eye looks like it has been injured, which could be why it is in a zoo and not released back into the wild by a rehabilitation center. I was surprised to see one in Tucson a few years back.

I think this bird is used each eye for focusing at different distance.

this seems to be an unique situation. Eye color is a polygenic trait. This above owl seems to have Heterochromia Indium which is due to an alteration in of the genes that controls eye color. Sometimes a medical condition known as Waardenberg Syndrome could also cause such a difference.
