The pet store near where I live has a young grey the ales staff says is a cross between a Timneh and a Congo.  Has anyone ever heard of that?  Are they ever found in the wild and if not, does this create an an ethical problem?

Any hybrid is an ethical problem.

They occur. Although not very often. Look much like the “Congo”.

Hybrids need to be loved as well.

They do occur in nature then?  That’s quite interesting. The one in the pet shop is almost indistinguishable from a Congo.  He has the same dark mandible, and is as large as a CAG, but retains the darker coloring on the back and has a maroon-ish tail.

Their ranges do not naturally overlap. So they would not hybridise naturally.

In this introduced distribution hybrids might occur. But we know nothing of this population. I like to know more.
