How do you make a canary nest?

I would first like to extend my deepest condolences regarding the loss of your canary. I have had MANY friends throughout my life that have accidentally left the cage door open. NONE of them EVER came back. Perhaps, yours will be different. I suppose we can hope for the best. The ONLY way to attract your canary is to have fostered a relationship in which it would not want to leave in the first place. For all we know, it has found it's natural home already. Chin up, and good luck.
