Each spring, thousands of snow geese stop at a Pennsylvania reservoir on their journey north to the Canadian Arctic, creating a dramatic display as the birds suddenly take flight in a swirling "bird tornado." The spectacle draws crowds of birdwatchers, though the growing snow goose population has also raised concerns about environmental damage and conflicts with farmers.

Why it matters

The annual snow goose migration is a beloved natural phenomenon in Pennsylvania, but the birds' surging population has led to conflicts with farmers and concerns about habitat damage in the Arctic. Wildlife managers must balance the interests of nature lovers, farmers, hunters, and conservationists.

The details

The snow geese stop at the Middle Creek Wildlife Management Area, a 6,300-acre property built 50 years ago to attract waterfowl. In recent years, the number of snow geese roosting at Middle Creek has grown to over 100,000 on the busiest days, with the birds circling and then lifting off the water in a dramatic "bird tornado" display. The spectacle draws about 150,000 visitors to Middle Creek each year, including around 1,000 hunters.

  • The snow geese arrive at Middle Creek each spring as they migrate north to their Arctic breeding grounds.
  • On the busiest day last year, around 100,000 snow geese were roosting at Middle Creek.
  • The single-day record for snow geese at Middle Creek was about 200,000 on February 21, 2018.

What they’re saying

“All it takes is for me to come out here on a really nice morning where there's a huge morning flight and I'm kind of reminded how awesome it is to see such a large number of such a beautiful bird. I never get sick of it.”

— Payton Miller, Environmental education specialist, Pennsylvania Game Commission

“For nature lovers, snow geese can be a delight, but for farmers, they're a pest. For hunters, they're food, but for animal rights advocates, they're a species that needs protection.”

— David M. Bird, Wildlife biology professor, McGill University

What’s next

The Pennsylvania Game Commission continues to monitor the snow goose population and migration, working to balance the interests of various stakeholders while addressing concerns about environmental damage.

The takeaway

The annual snow goose migration at Middle Creek is a beloved natural spectacle, but the growing population of these birds has also created complex challenges for wildlife managers as they navigate the competing interests of nature lovers, farmers, hunters, and conservationists.
