Black-rumped Waxbill

A small waxbill of semi-arid and dry scrubland habitats across sub-Saharan Africa and the Sahel zone, black-rumped waxbills have a distinctive crimson bill and rump that contrasts with their grey-brown body. They inhabit dry grasslands, savanna borders, and cultivated areas, feeding on small grass seeds. Though small and inconspicuous, they are a popular aviary bird kept throughout Europe and Asia for their delicate appearance and active, social behavior.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
