While known for their eery calls and cool looks, Common Loons [Gavia immer] are not made for non-aquatic landings or takeoffs.
Migrating Common Loons occasionally land on wet highways or parking lots, mistaking them for rivers and lakes. They become stranded without a considerable amount of open water for a long takeoff. A loon may also get stranded on a pond that is too small. – Cornell Lab of Ornithology’s All About Birds
