Recommended Harrison’s Bird Foods for canaries:

Adults:
HIGH POTENCY SUPER FINE for 3-6 months then ADULT LIFETIME SUPER FINE.

Chicks: 
NEONATE FORMULA for the first three weeks of life; this can be used up to weaning or switch to JUVENILE FORMULA for faster weight gain and fewer feedings.

Canaries sourced from chain pet stores may have a relatively short life compared to other species, but when fed Harrison's, they are often robustly healthy and longer-lived.

Canaries are tidy, non-destructive and easy to care for, but they do not necessarily like to be handled. They are appreciated most for their pleasant, melodious song. All male canaries sing, starting as early as three months of age. If a male canary becomes ill, it may stop singing until the following spring even though the initial illness has resolved. Canaries are not considered social birds. One bird kept as a single pet will be content.
