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.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.
