A giraffe at meal

I was able to capture a photo (top right) of a giraffe eating leaves of some twigs from a bag hanging on a tree at Woodland Park Zoo in Seattle. I believed someone at the zoo must have prepared these leaves for the two giraffes living here as lunch. It was interesting to see the giraffe close her eyes and enjoy the fresh green leaves with some white flowers as desserts.

Let us study the feeding and sleeping habits of giraffes from Wikipedia:

The giraffe browses on the twigs of trees, preferring trees of the genera Acacia, Commiphora and Terminalia, and it also eats grass and fruit. The tongue is tough owing to the giraffe's diet, which can include tree thorns. In Southern Africa, giraffes feed on all acacias, especially Acacia erioloba, and possess a specially-adapted tongue and lips that are tough enough to withstand the vicious thorns of this plant. A giraffe can eat 65 pounds (29 kg) of leaves and twigs daily, but can survive on just 15 pounds (6.8 kg). The giraffe requires less food than typical grazing animals because the foliage it eats has more concentrated nutrition and it has a more efficient digestive system. During the wet season, food is abundant and giraffes disperse widely, but during the dry season they need to congregate around evergreen trees and bushes. As a ruminant, it first chews its food, then swallows for processing and then visibly regurgitates the semi-digested cud up their necks and back into the mouth, in order to chew again. This process is usually repeated several times for each mouthful. The giraffe can survive without water for extended periods. A giraffe will clean off any bugs that appear on its face with its extremely long tongue (about 45 cm).

The giraffe has one of the shortest sleep requirements of any mammal, which is between ten minutes and two hours in a 24-hour period, averaging 1.9 hours per day.
