Bird Age Calculator
Estimate your budgie, cockatiel, lovebird or canary's age from visual signs — iris, cere, beak & plumage.
Honest estimate, not an exact age. This tool intersects month-ranges per visual sign and returns an age class plus a range (e.g. 6+ months). No calculator can pin a bird's exact birthday from looks alone — only breeder records or an avian vet can do that.

Verified examples
Budgie — deep blue cere, clear white iris ring, no head barring, bold throat spots → Adult, 6+ months (High confidence).
Cockatiel — pale grey face, dark soft beak, downy crest, barred under-tail → Juvenile, under 4 months (High confidence).
Lovebird — dark beak markings, dull smudgy forehead → Juvenile, under 3 months (High confidence).
Canary — clear unstreaked plumage, hard beak → Adult, 3+ months (Medium confidence).
All examples above were recomputed with the tool's own engine — they are outputs, not guesses.
Frequently asked questions
How accurate is this bird age calculator?
It gives an honest estimate, not an exact age. Each visual sign (iris ring, cere colour, head barring, beak markings) maps to a month range for that species, and the calculator intersects those ranges. You get an age class (Juvenile, Subadult or Adult) plus a range such as 6+ months. Only breeder hatch records or an avian vet can confirm a bird's exact age.
How can I tell my budgie's age?
Look at three signs. Young budgies (under 4 months) have head barring that reaches the cere, dark eyes with no white iris ring, and a pink or purple cere. The white iris ring appears around 6-8 months, head barring recedes, and the cere turns deep royal blue in males or tan-brown in females. A budgie showing all adult signs is estimated at 6+ months.
How do I know if my cockatiel is a baby or an adult?
Juveniles (under 6 months) have pale grey faces, dull cheek patches, short downy crests and dark soft beaks. Adult males develop a bright solid yellow face and lose the barring under the tail; females and juveniles keep that barring. A cockatiel with a bright yellow face and a clean unbarred tail is estimated at 9+ months.
How old is my lovebird?
Check the beak first: black or dark markings on the beak mean a juvenile under 3 months. As the dark markings fade and the beak turns solid bright coral, the bird is around 3-6 months (subadult). A lovebird with a fully bright beak, rich face colour and sleek plumage is estimated at 5+ months.
How can you tell a canary's age?
Young canaries have heavy brown streaking on their plumage and soft beaks with smooth pinkish legs. After the first moult (around 2-3 months) the streaks disappear and adult colour comes in. A canary with clear unstreaked plumage and a hard beak is estimated at 3+ months.
What does the year on my bird's leg band mean?
A closed leg band stamped with a year shows the bird's hatch year. Enter that year and the calculator raises the minimum estimated age accordingly - for example, a band stamped two years ago means the bird is at least 12 months old. Bands can be counterfeited or re-used, so treat it as supporting evidence, not proof.
Can this tool tell if my bird is male or female?
It gives basic visual sexing guidance per species, not a diagnosis. Budgies: adult males have deep blue ceres, females tan-brown or pale blue-white. Cockatiels: only normal-grey adult males get the bright yellow face and unbarred tail. Most lovebirds and many colour mutations cannot be sexed by sight at all - DNA testing is the reliable method.
When should I ask an avian vet instead?
Ask a vet when you need an exact age (for breeding, insurance or health baselines), when visual signs conflict, or when the bird shows health issues regardless of age. This calculator estimates age from appearance; it cannot diagnose illness, and sick birds of any age need professional care.
