Further north, rolling grassy hills enclose the tranquil beauty of the Momela Lakes, each one a different hue of green or blue. Their shallows sometimes tinged pink with thousands of flamingos, the lakes support a rich selection of resident and migrant waterfowl, and shaggy waterbucks display their large lyre-shaped horns on the watery fringes. Giraffes glide across the grassy hills, between grazing zebra herds.
