Weavers get their name because of their elaborately woven nests. The nests vary in size, shape, the material used, and construction techniques from species to species. Materials used for building nests include fine leaf fibres, grass, and twigs. Males break old nests down so that they can build a new green nest in its place and try to attract a female to that.
The female rhino is pregnant for about 18 months (depending on the species of the rhino), after which only one calf is born. At birth, this calf will weigh between 25 and 45 kilograms. It is born fairly weak but is able to stand up and begin walking within minutes of the birth, an incredible feat for one so young. Within the first few hours of its life, it will begin to suckle milk from its mother, which it will continue to do until about 18 months of age. The mother will allow her calf to drink milk exclusively for the first week or two. After that, she will take it to areas with soft grass and teach it to eat the young, juicy vegetation of the area. The rhino calf is born without a horn.
Elephants can also drink up to 50 gallons of water a day about as much as a standard bathtub holds. The elephant’s ability to locate underground water and dig pools helps provide many other species with water during droughts. Their unique trunk acts as part nose to assist in breathing and detecting odours, and part hand to assist with manipulating objects, social interactions, eating, dust bathing, drawing-up water and releasing it into the mouth for drinking.
