Here's my little guy again. He is by far the most social bird I've ever had (when I have him out of his cage, at least) but in his cage he is still timid.
The breeder thought he was a male, but I trust you all more. His cere is purple with a little blue around the nostrils. He is almost 9 weeks old. I find knowing when blue means male vs female to be kind of confusing...
He apparently can only climb the bars if there are head scratches involved!
This last image is not helpful at all... but I find it pretty funny. He loves my phone
