California condors are extremely rare (owing to excessive shooting, lead poisoning, and losses from other human-induced causes) and in 1982, only 27 remained in the wild. As a result of a conservation plan put in place by the United States government in 1987, there were 425 condors living wild or in captivity as of October 2014.
From 1987, when the last wild bird was captured, to 1992 condors were only found in zoos. In 1992 zoo-raised birds were returned to the wild.
It takes 57 days to hatch a condor egg and it may take an entire week for the chick to break out of the shell.
Condors are born with their eyes open.
Condors are social creatures, like wolves or primates.
Condors are the largest living birds, nearly 50 in. (125 cm) long with wingspans of from 9 to 10 ft (274 to 300 cm).
Voracious eaters, condors prefer carrion but will attack living animals as large as deer.
The purse crab, a giant relative of the hermit crab, finds food not in the water but in the trees. It uses its powerful pincers and long legs to climb coconut palms and snip off the young coconuts, which it then eats on the ground.
