Plains zebras have at least 6 different vocal calls. A two-syllable call is used to alert herd members to predators while snorts indicate happiness. They also use facial expressions to communicate. When greeting each other, they will stick their ears up and push their faces forward. When feeling threatened, they will press their ears against their heads.
Tusks are the only two front teeth of an elephant and grow throughout an elephant’s lifetime. Used to dig and find food, to play and fight, tusks are important tools although some elephants are born without one or both. Made of ivory, which has long been coveted by certain cultures, elephants have sadly been poached (killed) for their tusks.
The arrow-marked babbler lives in social groups of between 3 and 15 birds (six being the average) that defend large territories, with the size of the territory being dependent upon the number of individuals in the group. They feed on insects, spiders, and sometimes snails and lizards, as well as fruits. Foraging occurs near the ground, sometimes in association with other babblers or bulbuls. A dry gurgling babble “gra-gra-gra-gra-gra” is given by multiple birds, keeping the group together.
