On the other hand, a paler face can indicate illness or stress.

As its name suggests, the unstriped ground squirrel lacks the prominent stripes that characterize many other grounds squirrel species. It has a reddish-brown or greyish coat with a white underbelly and a bushy tail. These squirrels are excellent diggers and create extensive burrow systems.

The upland goose is primarily an herbivore, feeding mostly on seeds, leaves, stems, and other plant matter. They spend a significant amount of time preening to maintain the condition of their feathers. This behaviour helps keep their plumage waterproof and insulating. Despite their large size, upland geese are strong fliers. They have powerful wings that enable them to travel long distances during migration.


Underwing moths are famous for their cryptic colouration. While their forewings are often dull and camouflaged to resemble tree bark, their hindwings are brightly coloured with striking patterns of black, orange, red, or pink. Their colourful rear wing makes predators think that they are poisonous, however, they are not; it is a deceptive feature. If agitated, the underwing moths flash their rear wings to the predator and begin flapping their wings in a motion so fast that it looks like it’s vibrating. Underwing moths have particular sensory organs that allow them to “hear” the sound of bats from a distance.
