Quick Answer
Sandhill cranes typically stay in their wintering grounds for around 3-5 months, usually from October to February or March, depending on the specific location and availability of food.
Migration Patterns
Sandhill cranes are migratory birds that travel long distances between their breeding and wintering grounds each year. During their migration, they can cover over 2,000 miles, with some populations traveling as far as 3,000 miles. They tend to follow established flyways and stopover points, where they rest and refuel before continuing their journey.
Wintering Grounds
In North America, sandhill cranes typically winter in the southern United States, Mexico, and the Gulf Coast, with the largest concentrations found in the Bosque del Apache National Wildlife Refuge in New Mexico, the Padre Island National Seashore in Texas, and the Chincoteague National Wildlife Refuge in Virginia. These areas provide abundant food sources, such as wetlands, grasslands, and agricultural fields, which support the large populations of sandhill cranes.
Foraging and Feeding
During their stay in the wintering grounds, sandhill cranes engage in intense foraging activities, often spending up to 12 hours a day searching for food. They use a variety of techniques, including probing the ground with their bills, searching for seeds and grains in agricultural fields, and wading in shallow water to catch aquatic invertebrates and small fish. Their diet consists mainly of plant material, but they also consume small animals and insects to supplement their nutrient intake.
