For his new book "Tigers Forever," photographer Steve Winter traveled to India, Sumatra, Myanmar and Thailand capturing one of the most endangered big cats in the world.

A 10-month-old cub yawns, midday. Tigers are essentially nocturnal, most active from dusk to dawn, and tend to sleep during the heat of the day.
A wary 3-month-old cub briefly investigates the photographer's intrusion before ducking behind his mother. This tigress gave birth in the same remote cave where she was born.
A portion of the book’s proceeds will benefit partner organization Panthera’s Tigers Forever program.
