Following mom's lead. Thomson's gazelles, Maasai Mara, Kenya

There's something about the way animals move through the grasslands of the Maasai Mara, bathed in golden rays, that makes you pause and simply watch. This stretch of savanna in southwestern Kenya teems with wildlife—from elephants stomping through bushes to cheetahs scanning the horizon. Yet sometimes it's the smaller creatures that grab attention—like the Thomson's gazelles featured in today's image.

Known as 'tommies,' Thomson's gazelles are among the fastest animals in Africa, reaching speeds of up to 50 miles per hour. They thrive in the Mara's short grass plains, which provide a clear view of approaching predators. Though adults may seem to be grazing peacefully, their ears are always tuned to nearby movements.

Mating occurs year-round, peaking just before the rainy season. Males hold territories, waiting for females to pass through. After a five- to six-month gestation period, the female gives birth to one fawn, weighing around 4 to 6 pounds. For the first few weeks, the small gazelle stays hidden most of the day with the mother returning briefly to nurse. These early days are crucial as the young learn to run and blend in. Despite their delicate appearance, tommies are tough. Many join the great migration during the dry season, relying on their agility and the awareness of wildebeests and zebras to evade danger in search of greener plains.
