Tyrant flycatchers (Tyrannidae)

How long do least flycatchers live?

The oldest Least Flycatcher on record lived to 8 years, a record from a wild bird. That is a ceiling, not an average: most wild least flycatchers live only a few years.

Record age versus typical age

Longevity records come from birds that were marked and later found again, usually through bird banding, or from birds kept in zoos. They show what a Least Flycatcher can survive to, not what most do.

For small birds, the first year is the hardest. Many eggs and nestlings are lost to predators and weather, and young birds that leave the nest still have to learn to find food and avoid hawks and cats. A bird that survives its first winter has a much better chance of living several more years. That is why average lifespans in the wild are short even when the record is long.

Least flycatchers usually start breeding at about 1 year old. Each season a pair lays 3–6 eggs and raises 1 per season, with eggs taking 13–15 days to hatch.

How old is a Least Flycatcher when it first breeds?

Usually about 1 year old.

What is the oldest Least Flycatcher ever recorded?

8 years, according to the AnAge longevity database.

How many young can a Least Flycatcher raise in a year?

Pairs lay 3–6 eggs and raise 1 per season.
