The Quest for Northern Saw-whet Owls
A group of volunteer researchers, including the podcast's narrator, gathered at Hawk Mountain Sanctuary in Pennsylvania to study northern sawwhet owls, which are known for their small size and distinctive appearance. The team set up delicate nets and used recorded mating calls to attract the owls, marking the beginning of an immersive research experience to tag migratory birds. The goal was to understand their migratory patterns, lifespan, and behaviors such as fidelity to mates and wintering locations. Despite initial setbacks with empty nets during the first two checks, their perseverance paid off when they eventually captured two owls, which allowed them to study these captivating creatures closely.
