You can do some
fieldwork of your own by visiting tigers in zoos here in
the U.S. Some of the best zoos for tiger-watching are
noted on this map. Click a tiger pawprint to open a
window to that zoo’s Web site, where you’ll
find information about location, hours, and entrance
fees. (To close window and return to
nationalgeographic.com, click the square box in the
upper-left corner of the zoo’s window.)
