sandhill crane (Antigone, Canada) is a fascinating species that nests, overwinters, or stops over throughout North America. Many people know about their remarkable migrations, with millions of birds congregating in major staging areas across the country. But what do you know about sandhill crane nesting?
Sandhill cranes nest in wetland habitats, where they also forage. Nesting sites vary, but are usually on the surface of water, constructed from surrounding aquatic vegetation.
It’s not often that a person encounters a bird’s nest. They are often isolated inside wetlands where they are less likely to be disturbed. Since you may not be able to observe the nesting habits of these cranes in the wild, we’ve created this complete guide. In it, we take a deeper look at the most frequently asked questions about sandhill cranes’ nesting habits.

Where Do Sandhill Cranes Nest?
Sandhill cranes nest in wetlands that are flooded seasonally, such as swamps, marshes, or swales. Water level is important in nest site selection. Sandhill Cranes often nest in open water to depths of up to 40 inches. Nests may be attached to land or float on water.
Aquatic vegetation is also a key factor in nest site selection. Cattails, sedges, reeds, grasses, and thorny reeds are the primary vegetation found at nesting sites. To avoid disturbance, sandhill cranes typically build their nests away from the edges of wetlands, down to nearly 1,000 feet at their deepest points.
Although floating nests are most common, these cranes occasionally choose sites on dry ground. These sites are still surrounded by aquatic vegetation and close to water sources.

What does a sandhill crane nest look like?
Sandhill crane nests are built from floating aquatic plants, including cattails, reeds, and sedges. Branches, grass and moss are also included in the construction. Cranes use these items to form a mound over open water. Larger plant material forms the base, while the interior is lined with more malleable stems and twigs, forming a cup shape. Nests built on dry ground are not as easy to build. They are usually a simple platform of branches and vegetation.
Construction can last anywhere from a day to two weeks, and both male and female sandhill cranes will be involved in the building process. Cranes may continue to be added to the nest throughout the hatch to accommodate changes in water levels.
Floating nests are usually 10 to 16 cm above the water surface. On average, the nest reaches 98 cm x 113 cm. However, the length and width vary greatly depending on the location.

What time of year do sandhill cranes nest?
Migratory and non-migratory populations of Sandhill Cranes nest at different times of the year. Permanent residents may start spawning as early as December or as late as August, but most eggs are laid between January and May. Migrating cranes, on the other hand, tend to nest between early April and August.
How long do sandhill cranes nest?
Sandhill cranes have a long nesting season. For non-migratory species, the season can be as long as nine months, while migratory cranes build their nests for nearly five months. According to the Florida study, 19.5 days is the average time between the first hatch and the second hatch. This time period can be significantly reduced if the first clutch is lost.

How do sandhill cranes build their nests?
Early in the nesting season, sandhill cranes build their nests with dry plant material from the previous year’s sedges, cattails, reeds, reeds, and grasses. Cranes will add or re-nest greenery as the season progresses. Both men and women contribute to the building process. The female stands in the center of the nest and builds the nest around herself in a cup shape.

When Do Baby Sandhill Cranes Leave the Nest?
Baby sandhill cranes leave the nest within a day of hatching. They follow their parents through wetlands as they forage, and both parents directly feed their young for the first ten days. Then the foal gradually learns to feed itself. The fledgling dune makes its first flight between 65 and 75 days after hatching.
How many litters do sandhill cranes have?
Sandhill Cranes generally lay one clutch per year, laying one to three eggs. However, they can be nested up to 3 times. Re-nesting most often occurs after an unsuccessful litter.

Do sandhill cranes nest in the same place every year?
Sandhill cranes return to the same area year after year to nest. The previous year’s nest cannot be reused, but the birds will build new nests in the same spot or nearby.
What do sandhill crane eggs look like?
Sandhill crane eggs are usually olive to brown in color with dark, russet, or gray markings. Occasionally, the eggs are pure white. They are elongated ovals with an average size of 93.1 x 59.1 mm.

What month do sandhill cranes lay eggs?
Sandhill Cranes spawn in a wide range of months. Non-migratory populations lay eggs the longest – between December and August. The average egg laying date for Florida permanent residents is late February or early March. Sandhill cranes that participate in the annual migration usually lay their eggs in early April or May, but can nest as late as August.
Do sandhill cranes use nest boxes?
Sandhill cranes do not use nest boxes. They nest almost exclusively in wetland habitats and prefer to build floating nests on water. When nests are not in water, they are built on dry ground surrounded by aquatic plants such as cattails, sedges, and reeds.

Where Do Sandhill Cranes Nest at Night?
Sandhill cranes usually sleep at night and prefer to stand on one leg in shallow water with their heads buried under their shoulders. When nesting, the adults sleep in the same position, but both parents stay near the nest to protect the young.
Are Sandhill Cranes Nesting in Backyards?
Sandhill cranes are less likely to nest in backyards. These birds prefer dense, extensive wetlands and swamps with rich aquatic vegetation. To reduce disturbance and attack by predators, they usually nest at least 300 yards from the edge of the wetlands. That kind of solitude is unattainable in most backyards.
Expert Q&A
question
Do sandhill crane chicks return to their birthplaces as adults?
The BirdFact team
Sandhill Crane chicks typically stay with their parents for less than a year. After this time, they usually separate from their families during spring migration, or leave and establish their own breeding colonies when they find a mate.
While this is generally common behaviour, there are many examples of family units banding together, especially in wintering and breeding grounds. However, this rejoining is usually just moody.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
