Have had the Classic Canary song CD for several years and play it constantly. My rescued handicapped canary (no toes on one foot) is a partial red-factor mixed with yellow canary - type unknown. The Classic Canary CD is almost always playing - even through his molt. Both years since I have had this canary he resumed singing on November 6. Starts with very muted tones and within a few days is singing full force. Enjoys singing in the open doorway of his cage or on an outside perch.
