Longevity Record for a Brown-Crested Flycatcher Myiarchus Tyrannulus (Tyrannidae) From Ometepe Island, Nicaragua

Recapture analysis of banded birds helps researchers evaluate parameters such as longevity and survival, which provide insight into the life history, demography and general ecology of species and communities. However, long-term recapture data on Neotropical species are relatively scarce. As part of the Monitoring Overwinter Survival (MoSI) program, we have been banding and monitoring birds on Ometepe island in Lake Nicaragua, Nicaragua, intermittently since 2006. Here, we report the longevity of a Brown-crested Flycatcher Myiarchus tyrannulus which was banded in 2007 and recaptured in good health in 2023, making the bird at least 17 years 8.5 months old. After searching the extant literature for longevity records for all species in Tyrannidae, and finding published data on 41 of these, we believe our data provides a new published record for the family.
