- Sounds: Songs and Calls
- 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.
Physical Description: Adult Sandhill Cranes are recognized by their striking gray plumage, which can sometimes appear rusty-brown due to iron-rich mud they preen into their feathers. Their red forehead, white cheeks, and long, pointed black bill add to their distinctive look.
Subspecies Diversity: There are six recognized subspecies of Sandhill Cranes: Lesser, Canadian, Greater, Mississippi, Florida, and Cuban. These subspecies vary in size, with the Lesser Sandhill Crane being the smallest and the Greater Sandhill Crane being the largest.
Height and Weight: Standing at a height of 3 to 4 feet, Sandhill Cranes are impressive birds. Their weight ranges from 6.5 to 14 pounds, with males typically being larger than females.
Wingspan: With a wingspan stretching from 5 to 7 feet, Sandhill Cranes are powerful fliers. This extensive wingspan aids in their long migratory journeys, allowing them to glide efficiently.
Lifespan: Sandhill Cranes can live up to 20 years in the wild, though some have been known to reach up to 30 years. In captivity, their lifespan can extend even further due to the absence of predators and consistent food supply.
Mating Dance: One of the most captivating behaviors of Sandhill Cranes is their courtship dance. This elaborate display includes jumping, bowing, wing flapping, and loud trumpeting calls. These dances not only attract mates but also strengthen the bond between mated pairs.
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.
Eggs and Incubation: Typically, a female lays two eggs per breeding season. Both parents share incubation duties, which last about 30 days.
Chick Development: Sandhill Crane chicks, known as colts, are precocial, meaning they are born with downy feathers and can leave the nest within 24 hours of hatching. They start foraging alongside their parents almost immediately.
Parental Care: Both parents are involved in raising the chicks, teaching them essential survival skills like foraging and avoiding predators. The family unit stays together until the next breeding season.
Fledging: Chicks fledge, or develop the ability to fly, at around 65-75 days old. However, they remain with their parents for several more months, learning crucial life skills.
Predators: Common predators of Sandhill Cranes include raccoons, foxes, coyotes, and large birds of prey. Eggs and young chicks are particularly vulnerable to predation.
Defensive Behavior: When threatened, adult Sandhill Cranes use their powerful bills and strong legs to defend themselves and their young. They can deliver strong pecks and kicks to deter predators.
Wintering Grounds: In winter, Sandhill Cranes gather in large flocks in warmer climates. Popular wintering sites include Florida, Texas, and Mexico, where they find abundant food and suitable roosting areas.
