Leaf toughness influences colobus foraging effectivity. More durable leaves correlate negatively with ingestion fee (g/min) as they’re pricey when it comes to mastication, however positively with funding (chews/g).
People spend roughly 150 minutes actively feeding every day. In a montane habitat, colobus is recognized to utilize lichen as a fallback meal in periods of low meal availability.
Social patterns and morphology

Though there is no such thing as an apparent desire for tree kind, they’ve usually been noticed in Antiaris toxicaria.
Black-and-white colobus is essential for seed dispersal via its sloppy consuming habits, in addition to its digestive programs.
Predators and risk stage
Black-and-white colobus is a prey for a lot of forest predators and is threatened by attempting to find the bushmeat commerce, logging, and habitat destruction.
People are extra vigilant (conspecific risk) in low cover, in addition, they spend much less time scanning when they’re round acquainted group members versus unfamiliar.
