There are several sub species of congos. Congo is a basic a region where they come from. It is very possible that yours are Gahnas.

They have black beaks and bright red tails. They also tend to be a little small ( around 380 to 420 grams ). They also tend to be much darker in color.

They were quite common back in the days of imported birds twenty years ago. I have not seen a lot of them recently.

Species of red tailed african greys were referred to as gahnas, congos, cameroons. Once again this is depicted from the region they are from and also somewhat classified by size. The gahnas being the smallest and darkest, congos in the middle, and cameroons being the largest and almost light silver in color. Some were also said to be a through back to the King Jocos which had red feathering sort of sprinkled all throught their body.

This is only a guess, with over 20 years of experience behind it.

I never knew of the Ghana subspecies, that's interesting. Thanks Julie!

Actually, two of mine ARE imported, got them the other day. Imported birds still continue except for the protected ones like scarlet macaws.

Hi,
CAG's are larger then the TAG's. CAG's have black beaks and TAG'have horned colored beaks. CAG's tail feathers are red and TAG's are a maroon. CAG's are grey colored, while TAG's are black and grey. Camaroon is a region in Africa not a subspecies.
Read this and it will explain it more....
