Rob K. has a “Light question”
Mitch, I have read much and understood all of your points about lighting.
My bird is a Congo African Grey.
My concern is that I have also read articles about the danger of eye damage such as cataracts from such closeness and intensity of the light. At the equator, high noon footcandles range from 9-10,000 and cycle up and down moonlight to moonlight (.01 FC @ full moon) and between dawn & dusk (10 FC).
I have a full spectrum bulb in my ceiling 5′ above his cage.
