Sandhill Crane Family

The chicks remain with their parents until 1 or 2 months before the parents begin laying the next clutch of eggs. After leaving their parents, the chicks form nomadic flocks with other subadults and non-breeders. They remain with these flocks until they form breeding pairs and begin breeding between the ages of 2 and 7 years old. Sandhill cranes provide extended biparental care to their young. Both members of a breeding pair build the nest, incubate the eggs and feed and protect the chicks for up to 10 months after hatching. Sandhill cranes that reach independence are expected to live around 7 years. Sandhill cranes can live to at least 21 years of age. As a conspicuous and ground-dwelling species, Sandhill Cranes may face a variety of predators. Mammalian predators such as foxes, raccoons, coyotes, wolves, bobcats and lynxes readily predate cranes of any age, although they are a greater threat to young cranes. Birds that may predate young cranes or crane nests include corvids such as ravens and crows and smaller raptors, including hawks. Cranes of all ages may be predated by eagles, large owls and even Peregrine Falcons. Sandhill cranes often vigorously defend themselves from predators, especially when defending offspring which are not able to avoid ambushes as easily as their parents. When attacking potential avian predators they fly up at the predator and kick with their feet. When facing mammalian predators, they move toward the predator with their wings open and their bill pointed towards it. If the predator persists, the often hissing crane will attack, stabbing with their bill (which is powerful enough to pierce the skull of a small carnivore) and kicking with their feet.[14]
