Canary: lifespan, size, diet and care
Smoke, overheated non-stick pans and air fresheners can kill it: never in the kitchen, and keep the room at 18–20 °C (64–68 °F).
Take the quiz: is it right for you?

Before it arrives
- Best as a pair: the German Animal Welfare Federation says never keep one alone (two, or a group of at least four), while Merck says canaries are territorial and do well alone or in pairs
- An aviary at least 2 m long, 1 m wide and 2 m high (about 6.5 × 3.3 × 6.5 ft) for 2 to 6 canaries; at the very least, a cage where it can stretch its wings in every direction
- Natural branches of different thicknesses as perches; no mirrors, fake birds or sandpaper perches
- Several feeders and water bottles (ideally one per bird) and a bath dish
- Paper on the floor and a lamp with UVA and UVB if it lives only indoors
- Good seed or pellets, a cuttlebone and grit
- A bright, quiet spot at 18–20 °C (64–68 °F), never the kitchen, with no smoke, air fresheners or overheated non-stick pans
- A safe room where it can fly free every day, for a few hours
Its home: temperature and light
- The room
- 18–20 °C (64–68 °F)
- Light
- 12–14 hours a day
- UVB lamp
- needed
What it eats and how often
1–2 teaspoons of seed a day, plus vegetables and cuttlebone
- Adults: every day
One to two teaspoons of good-quality seed per canary a day (or complete pellets, which the RVC says are better balanced), plus fresh herbs and vegetables, very little fruit, a cuttlebone for calcium and a little grit. Remove old food every day.
Vaccines and checkups
Usually none: there are a few bird vaccines, but most pet birds don't get vaccinated. Ask your vet.
A checkup at the vet every year. Once a year, with an avian vet.
