Congo x Timneh African grey hybrids tend to be slightly larger than pure Timnehs; having medium-grey plumage with a muddy upper mandible and mixed maroon & red tail. For several decades after Timnehs were first imported, hybrids of the two were somewhat common due to the belief that they were the same species. Today, they are quite rare and believed to be fertile.
The first potential report of this hybrid was within the collection of G. Palmerin in a 1928 article of Aviculture Magazine; “A Gray Parrot which had the completely black beak of the ordinary psittacus erithacus, but the dark slaty crimson tail of P. timneh”.
