Notes

artic fox : The tundra is one of the driest and coldest places on earth. In winter, it is covered with ice and snow. In summer, the ground is soggy and wet .Fox families live in dens. A den might be in a mound on the open tundra, under a pile of rocks, or in the side of a cliff. A fox den has many tunnels with several entrances. flamingos: Flamingos build very interesting nests. A flamingo nest is not fancy—just a mound of mud, maybe 12 inches high—but it is carefully made. The nest needs to be high enough to protect the egg from flooding and from the occasional intense heat at ground level. Both the male and female build the nest by drawing mud toward their feet with their bills. Flamingos lay a single large egg, which is incubated by both parents. tiger: A tiger’s night vision is 6 times better than a human’s.
