1. Spur-thighed Tortoise (Centrochelys sulcata): This large tortoise has a brightly colored yellow or orange head, neck, and legs, which serves as a warning to potential predators that it is poisonous.
2. Heuglin's Robin-Chat (Cossypha heuglini): This small passerine bird has bright blue and orange plumage. Its bold coloration warns predators that it is poisonous due to its diet of toxic insects and plants.
3. Red-billed Quelea (Quelea quelea): These small, gregarious birds form vast flocks and use their bright red bills and black plumage to signal their large numbers and potential toxicity to predators.
4. Southern Ground Hornbill (Bucorvus leadbeateri): This large, terrestrial bird has a bright red, casque-like structure on its head and a black and white body. Its appearance warns predators of its formidable defense mechanisms, including its powerful bill and sharp claws.
5. Striped Skunk (Mephitis mephitis): Although not exclusive to the savanna, striped skunks are found in some savanna regions. They use their contrasting black and white stripes to signal to predators that they can spray a foul-smelling substance as a defense mechanism.
6. Poison Dart Frogs (Dendrobates spp.): While not native to the African savanna, some poison dart frogs inhabit savanna-like environments in Central and South America. Their bright coloration, often consisting of vibrant yellows, reds, and blues, serves as a warning to potential predators about their toxic skin secretions.
