Roan antelope
Roan antelope are found in woodland and grassland savanna, mainly in the tropical and subtropical grasslands, savannas, and shrublands biome, which range in tree density from forest with a grassy understorey (such as central Zambezian Miombo woodlands) to grasslands dotted with few trees, where they eat midlength grasses. They form harem groups of five to 15 animals with a dominant male. Roan antelope commonly fight among themselves for dominance of their herd, brandishing their horns while both animals are on their knees.
Elephants in Thailand
Elephants are herbivores, consuming ripe bananas, leaves, bamboo, tree bark, and other fruits. Eating occupies 18 hours of an elephant's day. They eat 100-200 kilograms of food per day. A cow (female) will eat 5.6 percent of her body weight per day. A bull (male) will eat 4.8 percent. Thus a 3,000 kilogram cow will consume 168 kg per day, a 4,000 kg bull 192 kg per day. As elephants can digest only 40 percent of their daily intake, the result is dung amounting to 50–60 kg daily. As elephants will not eat in unclean surroundings fouled by dung, their instinct is to roam to a new area.
