Wyoming suppors approximately 20% of the Rocky Mountain population (RMP) of greater sandhill cranes (Grus canadensis tabida), as well as a number of whooping cranes (Grus americana) from the Grays Lake, Idaho flock. Cranes begin arriving on post-migration staging areas in Wyoming in mid-March and disperse to summer habitat in April or May, depending on snow cover. Fall pre-migration, staging peaks around mid-September; most cranes leave the state by 1 October. Wet meadows and gram fIelds were the major habitat types used by cranes in Wyoming 1985-1987. Use in these types ranged from 69- 100% of total observations in any given 2-week period. Important grains included barley, wheat and oats. Wet meadows were typically either seasonally flooded wetlands or flood-irrigated haylands. Alfalfa fields and cattailbulrush (Typha sp./Scirpus sp.) marshes were also important habitats for cranes.
