Sandhill Cranes and Other Migratory Birds

The Sandhill Cranes are currently at the Preserve.

Sandhill cranes begin to arrive in late September/early October.

You’ll likely start seeing them in the wetlands near the trails in mid-October.

The height of the Sandhill crane season is December. During February and early March cranes will likely be leaving in groups. By mid-March, they are generally gone.

The ponds in the wetlands are flooded on a rotational basis to meet the needs of migrating waterfowl. To learn more about flooding and managed wetlands, click here.
