Yes showing your new bird what you are eating does help...also..if you find he will not shred paper or chew on wood you may need to show him how to do that too..it happens. I have shredded lots of paper with my teeth..shhh don't tell normal non-bird people that!
Warm foods, you can also try offering bird bread if you bake it, Mashes, anything that YOU will eat also you could share..try and not allow salts/sugars/too much fat/oils....LOL. Sorry i know if you dont cook specifically for your bird.
You could try some whole grain cereal also..like rasin bran or a bran with no sugar. YOU have to eat it too..see if he will take it off the spoon.
Also remembering Mayson...I would not allow that bird on your shoulder until you 2 know each other better! This next couple of weeks you will be tested, and you wouldnt want to go missing an ear or eyeball would ya? You dont know him/her well enough, and trust me..it all changes so fast! Give him/her time to become aquainted with the newness....then the fun loving, hyper active, crazy running, I love those darn BGM's come out! I love them!
