Timneh African Grey

Timneh African Grey Parrot (Psittacus erithacus timneh): These are smaller in size, have a darker charcoal grey colouring, a darker maroon tail, and a light, horn-coloured area to part of the upper mandible. The timneh grey parrot is endemic to the western parts of the moist Upper Guinea forests and bordering savannas of West Africa from Guinea-Bissau, Sierra Leone and Southern Mali east to at least 70 km (43 mi) east of the Bandama River in Ivory Coast. It is often called a "TAG". As pets Timnehs begin learning to speak earlier than Congos, and are often said to be less nervous around strangers and novel situations.
