How long do yellow-billed cuckoos live?
The oldest Yellow-billed Cuckoo on record lived to 5 years, a record from a wild bird. That is a ceiling, not an average: most wild yellow-billed cuckoos 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 Yellow-billed Cuckoo 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.
Yellow-billed cuckoos usually start breeding at about 1 year old. Each season a pair lays 1–5 eggs and raises 1–2 per season, with eggs taking 9–11 days to hatch.

5 years, according to the AnAge longevity database.
