Some migratory populations of sandhill cranes face population threats due to interspecies competition with snow geese. Since the 1990s, snow geese have eaten waste corn on which the cranes also rely prior to migration. Sandhill crane populations are also threatened by hunting. Hunting cranes is legal throughout the states of the Central Flyway, from the Dakotas and Wyoming south to Oklahoma and Texas. Nebraska is the sole state along the Central Flyway where hunting cranes is illegal. Despite losses from hunting, interspecies competition and other pressures such as habitat loss, the species has expanded its range. Since the early 2000s, the sandhill crane has expanded both its winter (nonbreeding) and breeding ranges northward, including into upstate New York. In the 21st century, parts of the Midwestern United States have seen an extensive rebound of the species.
