It may take some time. I think I remember reading somewhere that birds even practice their songs in their sleep. I think the researchers monitored brain waves or some such thing to show that the birds would silently rehearse in their sleep.
Even more trivia: birds only sleep half their brains at a time. One eye generally stays open. Though the original study was on ducks, I saw this repeatedly with my cockatiel, who always slept with his "outside" eye (the one toward the window) open. (Past tense, because the sweet thing passed away a few weeks ago at the grand old age of 11.)
My canary is tweeping little experimental snatches of tunes today. His mourning dove call took about 3 weeks to perfect, so I'll give him some time.
