Giraffes in the Masai Mara National Reserve, Kenya

Where shadows stretch tall. Giraffes in the Masai Mara National Reserve, Kenya

As the sun sinks low in the Masai Mara National Reserve, the silhouettes of Masai giraffes rise against a blazing sky and open plains. Another day comes to an end in the reserve, which stretches across about 580 square miles in southwestern Kenya, bordering Tanzania's Serengeti National Park. It is a vast expanse, one of the world's greatest wildlife arenas. Rolling grasslands, scattered acacia trees and the life-giving Mara River set the stage for unforgettable encounters.

Among the stars of this landscape are Masai giraffes. Their coats are marked with bold, jagged patches, each pattern as unique as a fingerprint. They spend most of their days browsing treetops, skilfully using their long tongues to pluck leaves from between sharp thorns. They may move with calm grace, but these towering animals can burst into a gallop at surprising speeds of up to 35 miles per hour. Their presence is a reminder that the untamed world still holds its wild rhythm.
