This last weekend was a good one for birdwatchers at Freezout Lake west of Great Falls. Some folks from Hamilton were there and experienced the spectacle of an estimated 25,500 Snow Geese and Ross's Geese, along with about 2,400 migrating Tundras and Trumpeter Swans in their annual spring stopover at the ponds of the Freezout Lake Wildlife Management Area.

The Montana Fish, Wildlife and Parks daily updates show Sunday, March 21st, as the largest migration day so far this season. Click on "migration status" in the top right of that Freezout page. The site is updated on a regular basis. Compared to the average migration numbers from years past, the observers noted that the geese numbers are below average, but are increasing, while the swan populations have dropped a bit, but this is one of the main weeks of the migration. Ducks are also gathering at the lake.

Because of it's location along the Rocky Mountain Front, on a main flyway, Freezout usually has visits from over 230 species of birds throughout the year, but the days of the migrating geese and swans are memorable.
