Michael G. relates:
I have a mystery! I have two African Greys.
But first, a bit of history.
They are in a large cage 3′ deep, 6′ high, and 5′ long.
I rehomed them after 18 and 20 years with the female the oldest and banded while the male doesn’t have a band.
She is pretty docile while he, after 2 years is still a bit afraid and likes to bite when she is startled.
