Research-reading information, not veterinary advice or an individual prognosis. No countdown or remaining-years estimate. A present health concern needs an appropriate avian professional; do not wait for a worksheet or an app reply.
Record and maximum
A maximum is the largest value observed in the defined dataset. A record age may be exceptional rather than representative. This site uses those words to describe a statistic, not a recommended age target, a limit for all birds or a guarantee about a living individual.
Median and life expectancy
A median is a middle value in the defined observations. Life expectancy is an expected lifespan under the method and population used to estimate it. The cited papers use distinct analyses. The terms should not be swapped simply because a headline calls both of them an average.
Population and cutoff
The population is the set of animals or records to which the analysis applies. A cutoff determines which observations are included at a stated time or under an age rule. Neither tells a reader that a pet outside that set has the same future as the research summary.
Uncertainty and prognosis
Uncertainty is a limit on what the data and method establish. A prognosis concerns an individual's expected course in its circumstances. These research-reading pages provide no individual prognosis. An unknown source detail stays unknown; it does not become a zero, a deadline or a reassurance about health.
