Diet

Whooping cranes eat a variety of things, including insects, frogs , small birds, rodents, minnows , and waste grains. Blue crabs and clams are especially important food items on the wintering grounds .

Reproduction

Whooping cranes can live more than 20 years in the wild. They are capable of breeding after three years and mate for life. Nest construction begins in late April. Nests are made of bulrush and are located in tall vegetation near water. Typically, two eggs are laid each year and both parents assist in the care of the young. Young stay with their parents during their first winter.
