What this calculator does
Pet bird age works out human-equivalent age for a pet bird, scaled by its species’ typical lifespan. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaHuman-equivalent age = bird’s age × (human average lifespan / species average lifespan)
The inputs explained
| Field | What to enter |
|---|---|
| Species | Choose from Budgerigar / parakeet, Canary, Lovebird, Cockatiel, Conure, Cockatoo, African grey parrot, Macaw. |
| Bird's age (years) | A number, measured in years. Starts at 2. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with bird's age
Every other input is held at the calculator’s starting values while bird's age varies. Select any row to load that scenario into the calculator.
How the answer changes with bird's age
| Bird's age (years) | Human-equivalent age | Species average lifespan used | Note |
|---|---|---|---|
| 1 | 10.4 years | 7 years | A rough proportional estimate (bird age × human lifespan ÷ species lifespan); birds reach maturity far earlier than the ratio implies |
| 1.5 | 15.6 years | 7 years | A rough proportional estimate (bird age × human lifespan ÷ species lifespan); birds reach maturity far earlier than the ratio implies |
| 2 | 20.7 years | 7 years | A rough proportional estimate (bird age × human lifespan ÷ species lifespan); birds reach maturity far earlier than the ratio implies |
| 3 | 31.1 years | 7 years | A rough proportional estimate (bird age × human lifespan ÷ species lifespan); birds reach maturity far earlier than the ratio implies |
| 4 | 41.5 years | 7 years | A rough proportional estimate (bird age × human lifespan ÷ species lifespan); birds reach maturity far earlier than the ratio implies |
| 6 | 62.2 years | 7 years | A rough proportional estimate (bird age × human lifespan ÷ species lifespan); birds reach maturity far earlier than the ratio implies |
