There is a bright circle on the eye that looks like a reflection except that there is nothing to reflect.

Thanks.
That’s what I thought until I moved the light to the other side of the rabbit. The only thing at that position is the camera.
Then what kind of light shines on the rabbit ?
If you moved the lamp away!
Is there an emmisive plane in the scene?
There is no emissive anything in the scene.
Ooo a mystery, could you share the blend file? I am curious!
It is the Lamp.
The Sun lamp is a uniform directional light so it doesn’t matter where the lamp is in the scene.
You can test this by turning the lamp off- the reflection goes, rotating the lamp also moves the reflection too 
Thanks Michael, I hadn’t realized that the sun was a uniform directional lamp
