What is the typical lifespan of a saw-whet owl in the wild, and how does it compare to those in captivity? Are there specific factors that influence their lifespan in both environments?
Answer
The lifespan of a saw-whet owl (Aegolius acadicus) in the wild is typically around 3 to 4 years. However, some individuals have been recorded living up to 7 years or more under favorable conditions. In captivity, where threats from predators and food scarcity are minimal, saw-whet owls can live longer, sometimes exceeding 15 years. Factors such as habitat quality, food availability, and predation pressure can significantly affect their lifespan in the wild.
