Surprisingly little is known about the basic biology of many large raptor species. Zoos and wildlife rehabilitation centers can help remedy this knowledge gap by providing a wealth of data on species whose in situ counterparts are difficult to study. We present one such example here by recording multiple new longevity records for the Barred Owl (Strix varia Barton, 1799). At 34 years and 1 month of age, the longest-lived new record surpasses the previous oldest known individual by a decade. Along with the additional new and already available longevity data we reviewed, the information provided here will prove useful for those working on many aspects of owl biology.
