The common crane, also known as the Eurasian crane, is a bird of the family Gruidae, the cranes. A medium-sized species, it is the only crane commonly found in Europe besides the demoiselle crane and the Siberian crane. Along with the sandhill and demoiselle cranes and the brolga, it is one of only four crane species not currently classified as threatened with extinction or conservation dependent on the species level. Despite the species' large numbers, local extinctions and extirpations have taken place in part of its range, and an ongoing reintroduction project is underway in the United Kingdom.
The tundra swan is a small swan of the Holarctic. The two taxa within it are usually regarded as conspecific, but are also sometimes split into two species: Bewick's swan of the Palaearctic and the whistling swan proper of the Nearctic. Birds from eastern Russia are sometimes separated as the subspecies C. c. jankowskii, but this is not widely accepted as distinct, with most authors including them in C. c. bewickii. Tundra swans are sometimes separated in the subgenus Olor together with the other Arctic swan species.
The whooper swan, also known as the common swan, pronounced hooper swan, is a large northern hemisphere swan. It is the Eurasian counterpart of the North American trumpeter swan, and the type species for the genus Cygnus.
The sandhill crane is a species of large crane of North America and extreme northeastern Siberia. The common name of this bird refers to habitat like that at the Platte River, on the edge of Nebraska's Sandhills on the American Great Plains. This is the most important stopover area for the nominotypical subspecies, the lesser sandhill crane, with up to 450,000 of these birds migrating through annually.
The whooping crane is the tallest North American bird, named for its whooping sound. It is an endangered crane species. Along with the sandhill crane, it is one of only two crane species native to North America. The whooping crane's lifespan is estimated to be 22 to 24 years in the wild. After being pushed to the brink of extinction by unregulated hunting and loss of habitat to just 21 wild and two captive whooping cranes by 1941, conservation efforts have led to a limited recovery. The total number of cranes in the surviving migratory population, plus three reintroduced flocks and in captivity, now exceeds 800 birds.
The trumpeter swan is a species of swan found in North America. The heaviest living bird native to North America, it is also the largest extant species of waterfowl, with a wingspan of 185 to 250 cm. It is the American counterpart and a close relative of the whooper swan of Eurasia, and even has been considered the same species by some authorities. By 1933, fewer than 70 wild trumpeters were known to exist, and extinction seemed imminent, until aerial surveys discovered a Pacific population of several thousand trumpeters around Alaska's Copper River. Careful reintroductions by wildlife agencies and the Trumpeter Swan Society gradually restored the North American wild population to over 46,000 birds by 2010.
The Ruby Lake National Wildlife Refuge is located in southwestern Elko County and northwestern White Pine County in the northeastern section of the state of Nevada in the western United States. Established in 1938, it encompasses 37,632 acres (152.29 km2) of wetlands in Ruby Valley, just east of the Ruby Mountains and just south of Harrison Pass. It is 16 miles (26 km) long, up to 3 miles (4.8 km) in width, and lies at an elevation of 6,000 feet (1,800 m). Once the bed of a 200-foot (61 m) deep lake, it is now a network of spring-fed marshes and shallow ponds serving as a habitat for hundreds of species of native and migratory birds and mammals.
Monte Vista National Wildlife Refuge is a United States National Wildlife Refuge located in southern Colorado. The refuge is located in the San Luis Valley south of the town of Monte Vista, Colorado in southeastern Rio Grande County, Colorado, in the watershed of the Rio Grande. It was established in 1953 by the Migratory Bird Conservation Commission to provide a habitat for wildlife, particularly waterfowl, in the San Luis Valley.
Red Rock Lakes National Wildlife Refuge is a remote refuge located in the high elevation of the Centennial Valley, in the southwestern region of the U.S. state of Montana. Adjacent to Gallatin National Forest and near Yellowstone National Park, the refuge is an integral part of the Greater Yellowstone Ecosystem. Red Rock Lakes is best known for being the primary location for the efforts saving the trumpeter swan from extinction, which by 1932 had fewer than 200 known specimens in the United States and Canada. By the year 2002, an estimated 3,000 trumpeters were wintering on the refuge, many having migrated south from their summer range in Canada. The trumpeters are now so plentiful that efforts are being undertaken to help them reestablish historical migratory routes to areas further south in the Rocky Mountains and the Great Basin region. The elegant trumpeter swan is North America's largest waterfowl, with a wingspans of 8 feet and they can weigh up to 30 pounds (13 kg).
Lacreek National Wildlife Refuge is a National Wildlife Refuge of the United States located in South Dakota. It covers 16,410 acres (66.4 km2) and is managed by the United States Fish and Wildlife Service.

Glacial Ridge National Wildlife Refuge was created on October 12, 2004, the 545th National Wildlife Refuge in the United States. Its creation was the result of cooperation between at least 30 agencies or governmental entities. The creation of the refuge was spearheaded by The Nature Conservancy, and the initial endowment of 2,300 acres (9.3 km2) of land was donated by the Conservancy. In light of its planned final size of 37,756 acres (153 km2), it is described by the US Fish and Wildlife Service as "the largest tallgrass prairie and wetland restoration project in U.S. history."
