We all "leave the nest” eventually, and animals do, too. Here we follow different creatures from all sorts of environments as they leave home and venture off to make their own place in the natural world. Some walk (jaguars), some crawl (crabs), some swim (sharks). Some leave as soon as they’re born (salamanders), and others leave after several years (elephants). Albatrosses fly across oceans while hedgehogs walk only a short distance away. And songbirds even come back.
