  • Length: 47.0″ – 60.0″ in (120 – 152 cm).
  • Weight: 7.5 – 10.8 lbs. (120 – 173 oz.).
  • Wingspan: 72.0 – 78.7 in (183 – 200 cm).
  • Order: Gruiformes
  • Family: Gruidae
  • Genus: Antigone
  • Species: A. canadensis
  • Scientific Name: Grus canadensis
  • Lifespan: 20-30 years in the wild. 80 years in captivity.
  • Range: The Sandhill Cranes are the most common crane in North America. Their range extends from southeastern Alaska to southern Canada and south through the United States to northeastern Mexico. 
  • Migration: They spend their winters at marshes, swamps, and other wetland habitats in Texas, Louisiana, Florida, Mexico and Central America. They have been known to migrate as far south as Panama during winter to escape the cold weather. Their migration pattern can be seen from October to March, when they fly back north again.
  • Habitat: Swamps, bogs, vernal pools,  prairies, wet meadows, open wetlands, freshwater marshes, grasslands, agricultural fields, and savannas.
  • Diet: The sandhill crane’s diet consists of plant material (seeds, leaves & berries), small vertebrates (frogs, fish, snakes), insects (grasshoppers, beetles, ants, flies and caterpillars), crustaceans and mollusks.
  • Global Population: est. 650,000 individuals.
  • Conservation Status: Not extinct (Listed Endangered Species).
  • Breeding Period: Non-migratory birds lay their eggs between December and August, and migrating birds will lay their eggs between Feb and April.
  • Incubation Length: 29-32 days.
  • Clutch Size: 1-3 eggs.
  • Number of Broods: 1 Brood.
  • Fledgling Period: 9 to 10 months.
  • Nesting Habits:  Sandhill cranes nest in remote wetlands such as marshes, mudflats, shallow lakes, or bogs, and prefer to be near the dense cover of tall grasses. They will often build their nests on hummocks made by prairie dogs or other ground dwelling rodents.
  • Nesting Materials: Sandhill Cranes build their nests from various materials, but they typically use cattail or tall grass to construct a large cup shaped nest that is almost 4 feet in diameter. The nest is constructed out of long stems, held together with the help of mud, which helps hold everything together. Both mates will gather material for the project. 
  • Mating Season: The mating season for Sandhill Cranes is November to January with the egg-laying period lasting from February to March or April (depending on the region). 
  • Incubation: After the nest is finished, both adults will incubate the egg for *approximately* 29-32 days, during which time they may lose up to 1/3 of their body weight. The mother feeds her chick for about 4 weeks after hatching. The young are able to fly at 9 -10.5 weeks old, but are not yet ready to leave their nest until 10 months old.

50 Fascinating Facts About Sandhill Cranes

Species Overview: Sandhill Cranes (Grus canadensis) are among the oldest living bird species, with a fossil record dating back over 2.5 million years. They are found across North America, with some populations extending into northeastern Siberia.

Monogamous Bonds: Sandhill Cranes are known for their strong monogamous bonds. Once a pair bonds, they often stay together for life, working as a team to raise their young and defend their territory.

Migration Patterns: Sandhill Cranes are renowned for their lengthy migrations. Some populations travel over 3,000 miles from their breeding grounds in Canada and Alaska to their wintering sites in the southern United States and Mexico.

Stopover Sites: During migration, Sandhill Cranes use key stopover sites like Nebraska’s Platte River, where tens of thousands gather to rest and refuel. These sites are crucial for their survival during long migratory journeys.

Diet: These cranes are omnivorous, feeding on a varied diet that includes grains, seeds, berries, insects, small mammals, and aquatic plants. Their diet changes seasonally based on food availability.

Feeding Behavior: Sandhill Cranes use their long bills to probe the soil and mud for food. They are also known to forage in agricultural fields, particularly during migration and winter.

Vocalizations: Sandhill Cranes are highly vocal birds, known for their distinctive, rolling “kar-r-r-o-o-o” calls. These calls can be heard from miles away and play a vital role in communication between pairs and within flocks.

Breeding Habitat: They prefer open wetlands for breeding, often selecting marshes, bogs, and wet meadows. These habitats provide the necessary resources for nesting and raising chicks.

Nesting: Sandhill Cranes build their nests on the ground, often in shallow water to deter predators. Nests are constructed from plant material like cattails, grasses, and sedges.
