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.
Dull-mantled antbird
The diet of the dull-mantled antbird is composed of insects and other arthropods; recorded prey items are spiders (Araneae), cockroaches (Blattaria), beetles (Coleoptera), crickets (Gryllidae), woodlice (Oniscidea) and indeterminate insect larvae. It feeds as an individual, as a pair or in small family groups, moving close to the ground – usually not more than 10 cm above the forest floor –, every now and then jumping up to a low branch to take a look around and immediately descending again. Its prey is usually caught by gleaning, pecked up from between the leaf litter or, after a jump up or a short flutter, from vegetation. It rarely rummages through the leaf litter to search for prey; rather, it will observe its surroundings tensely, beating down its tail forcefully and slowly raising it up again, and then strike directly at something that has attracted its interest. Small prey is devoured immediately; larger animals are beaten vigorously on branches to make them easier to swallow. The species will occasionally follow army ants but it is not an obligate ant-follower like some other true antbirds or ground antbirds (Formicariidae); while it may join mixed-species feeding flocks on occasion, it usually prefers to forage on its own or with its family.
