I really don't think there's anything wrong or amiss here, but we have noticed that Simo is generally a very silent bird. He does vocalize, most notably he has these silent but distinctive squawks. So far he seems to have learned no words - but he did learn to laugh, which he picked up literally in an hour after I started to go "hahaha" after him. I wonder, could this be a case of the "shy talker bird?" Meaning, he speaks when maybe we're not around to see it?
I'm honestly not bothered weather he'll ever learn to talk "human" or not, but I am curious if he does it when no one hears! I know that Ringnecks are good talkers, and we talk to him reguarly, repeating many words. At times I catch him moving his beak and I hear faint whispery sounds, but not words.
Or could he still be too young? I've heard that the age they properly pick up words can vary an awful lot. Some IRN learn it at only half a year old, some when a bit older. I'm not bothered if he's a silent thinker but it'd be nice to hear some thoughts on this.
