In this video segment from Wild Nevada, host Brian Wignall and biologist Cris Tomlinson discuss the greater sandhill crane, a large bird that stops in Nevada to feed on grains and other plant crops during its spring migration. Sandhill cranes mate for life, and the partners communicate with each other using a distinctive call. As one of North America's oldest bird species, dating back at least 9 million years, sandhill cranes protect themselves effectively against predators such as coyotes, relying on keen eyesight as one of their primary defense mechanisms.
