  • They appear from nowhere,

  • stoic sentinels in fields, farmlands, and shorelines.

  • For a time they become part of the landscape,

  • but soon they will be gone.

  • Each of these great nomads is on a lifelong journey, spanning continents in search of food.

  • Individual owls have been tracked moving from Alaska to the Canadian Arctic to Russia

  • over the course of just a couple years.

  • Some wander the pack ice, hundreds of miles from land where they feed in Arctic darkness on seabirds.

  • A summer of lemming abundance in the Arctic produced lots of young owls and

  • competition for food further north may have pushed them here.

  • Wet plumage in the early morning on the feet and under the tail

  • reveals they're not only preying on voles and rats

  • but also on shorebirds and waterfowl snatched from the water with their hooked talons.

  • For most of the day they roost motionless to conserve energy.

  • When one of these Arctic wanderers comes south to reside briefly in a farmer’s field,

  • we get to glimpse a moment in a long food-driven journey

  • that we as humans can hardly imagine.

They appear from nowhere,
