These
parrots are renowned for their high intelligence and speaking
abilities, which some parrot experts say Greys do with full
comprehension.Two subspecies are common
as companion parrots: the Congo and the Timneh.The
Congo is the larger of the two and typically is light gray with a
bright red tail.The Timneh
are darker and smaller compared to the Congo Grey. They also have
maroon colored tails versus the Congo's red tail. Regardless
of size and color, all Greys have the same potential for speaking and
replicating an astonishing range of sounds.As
with any highly intelligent creature, it takes time and patience on the
part of the owner for the Grey to reach its developmental capabilities.Greys are considered medium-sized parrots and
are suitable for a wide range of home environments.
