Spring Migration 2018 - Snow Goose Estimates

Due to a late winter storm, snow geese briefly stopped at the Refuge before being forced to travel back south when the Refuge received about 10" of snow the first week of April. When they made their return trip north, they moved very quickly through the Refuge. On 4/12/2018, 3000-5000 birds were observed using the Refuge. By 4/20/2018, it was estimated most snow geese had made their way into North Dakota. 

 

Spring Migration 2019 - Snow Goose Estimates

Due to extended winter conditions at Sand Lake Refuge, the snow geese migration concentrated to the surrounding counties as the birds made their way north. Only small, scattered flocks were observed near the Refuge in April as they made their way to North Dakota.
