Obviously a lot longer than some of us would believe.
I thought this information I can across recently on Ospreys was very interesting:
"According to the most recent estimates, about half of young Ospreys die in the first year; the mortality rate in subsequent years is between 16 and 19 percent. Available banding data (20,000 individuals have been banded in the last 60 years), indicates that Ospreys can live for 15 to 20 years; however, some individuals have lived much longer. The longevity record for the species is held by a banded bird that died, probably from a bullet, at age 35. Unfortunately, we don’t know whether this individual had bred every year up to its death. The greatest recorded number of breeding seasons for a single bird is 23." :flyaway:
