The Sandhill Crane (Scientific name - Grus canadensis) is a large crane that is found in North America and in Northeastern Siberia. They migrate South in winter and gather in large flocks in areas like New Mexico. Fossils suggest that this bird (or its ancestor) were present 2.5 million years ago.
The Sandhill Crane has a mostly grey body with a distinct red forehead, white cheeks and a dark bill.
