The Congo African Grey parrot (
Psittacus Erithacus Erithacus) is a, primarily grey (therefore the name "grey parrot"), colored bird with distinct bright red colored tail feathers. They are approximately 33 cm (13 inches) large and have dark grey/light black beaks whereas the sub-species, Timneh African Grey parrot (
Psittacus Erithacus Timneh), have different colored beaks - dark grey and beige, are smaller in size and have maroon colored tail feathers. CAG's can live to be older than 60 years of age and are highly intelligent birds. Studies conducted by Dr. Irene Pepperberg have shown that their intelligence is comparable to that of a three year old human child. One of the most famous CAG's was Alex, one of the parrots taught and studied by Dr. Irene Pepperberg. Alex could say over 100 words (labelling objects, colors etc.), tell the difference between different matter (wood, whool etc.), could count objects, up to six, and a lot more!
CAG's have very dark, almost black, colored eyes when they are newly hatched and at around 6-7 months of age their eyes start to turn brighter in color (light grey). When they become adults, at around 2-3 years of age, their eyes turn light yellow (se pic).
