Which pellets should you choose by age: juvenile, adult or senior bird?
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Pellets sold for birds aren't all interchangeable across ages: a growing juvenile needs more protein and fat than a resting adult, while a senior bird often benefits from a lower-fat formula enriched with antioxidants. Few manufacturers offer a full range by age, which means reading the label rather than trusting the product name alone. Find more nutrition guidance in our food section, part of our bird hub.

Why do nutritional needs change with a bird's age?
A landmark review by Elizabeth Koutsos, Kevin Matson and Kirk Klasing, published in 2001 in the Journal of Avian Medicine and Surgery, synthesises the nutritional needs of psittacines across life stages and notes that malnutrition remains one of the most common diagnoses in captive birds, largely due to a diet poorly matched to the individual's age and activity level (see the study). Bone growth and feather development in the young, muscle maintenance in adults, a slowing metabolism in seniors: each stage places different demands on the body.
Which pellets should you choose for a growing young bird?
A "juvenile" or "growth" pellet usually carries a higher protein level, around 18 to 20% versus 12 to 14% for an adult formula, along with more fat, to support skeletal formation and the first full moult. This formula stays useful until the species reaches sexual maturity, which ranges from a few months for a budgie to several years for a large macaw.
What should you prioritise for a healthy adult bird?
- A "maintenance" pellet, lower in fat than a growth formula, to prevent weight gain in a bird that's not very active in its cage.
- A share of fresh fruit and vegetables alongside it, covered in our guide on safe fruits and vegetables for birds.
- Regular weight checks, rather than relying on visual judgement alone, using a precision scale.
Should you adjust a senior bird's diet?
Past the halfway point of the species' life expectancy, a lower-fat senior formula limits weight gain linked to declining activity, while added antioxidants and glucosamine support the joints of a bird that perches less often. A senior bird that suddenly refuses its usual pellets or loses weight with no diet change should see an avian vet rather than have its diet altered blindly.
Frequently asked questions
Can you feed adult pellets to a juvenile?
Not ideal long-term: the lower protein level can slow growth; it's better to stick with the age-appropriate formula until growth is complete.
At what age does a bird become "senior"?
It varies hugely by species: as early as 7-8 years for a small parakeet, rarely before 20-25 years for a large, exceptionally long-lived parrot.
Should you switch formulas abruptly at each stage?
No, a gradual transition over one to two weeks, mixing the old and new formula, avoids refusal and digestive upset.
