Sounds like a very loved little bird, he's lucky to have you. Sounds like normal behavior, just make sure he's not eating anything that could potentially be harmful like chocolate & avocado, or houseplants that could impact his health. I actually had to lol while reading your post just imagining this little character..I too use to have a little song canary that was given lot's of free flight, but unfortunately he flew out the door..so please beware of open doors and windows. Enjoy your feathered friend.
