Most 'birds of a feather' flock together, but some, apparently,
go astray - like the goose who befriends a tortoise and even protects
the tortoise's nice fresh pile of veggies from the thieving intentions
of other geese. The tortoise and the goose, the dog and the chimp, the
lion and the coyote, and many more of nature's odd couples promise to
provide hours of entertainment and insights this season in PBS Nature's new series Animal Odd Couples.
