Critter - I definately need to check out this catalog! I didn't know Fosters and Smith had a bird specific one, I get the dog one...
I know that their articles tend to be for the most part pretty informative but I have to disagree with what they are saying about moving your bird away from one who already talks.
It's not uncommon at all for Grays to be "late bloomers" in the talking department. 7 months old is young! An African Gray will normally absorb like a sponge- then when he's ready- start speaking with amazing ability - leaving you wondering "How the heck did he learn that one!?"
I could be way off the mark here but I believe that by working with him consistantly on phrases (and the sounds- he'll pick those up naturally from his environment) - he should speak! It may not be until he's a year or a little over, but it seems to me that having a prolific talker near him can only benefit him.
Grays are such unique birds - their intelligence is quite remarkably high - and of course they are known for their huge vocabularies , and ability to apply language to proper situations!
They don't begin speaking as quickly as other birds seem to though. They are slow to mature.
I used to have a great web resource with information about Dr. Irene Pepperberg's (gosh I hope I got that name right) ongoing research regarding Grays and their speech and intelligence. It's totally engrossing information if you've never read about her work.
I'll see if I can find it again and post it ... it's probably easy to find by looking up her name though ... hrrm.
I'm just a little surprised that the catalog gave that information, especially regarding Grays.
If I'm totally off-base here , someone please correct me?
