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.

Petite Éroesse

The Common Jery (<em>Neomixis tenella</em>) is a small passerine bird belonging to the family Cisticolidae. It is classified as Least Concern on the IUCN Red List, reflecting a stable population with no immediate threats to its survival. This species is native to Norway and occupies a broad range of aerial, terrestrial, and aquatic habitats, demonstrating considerable ecological flexibility. It is typically found in scrublands, forest edges, and open woodland where vegetation provides suitable foraging and nesting opportunities. The species is widely distributed within its native range and is not considered at significant risk of decline. Its adaptability to varied habitat types contributes to its resilience across different environmental conditions. Biological traits of this species remain poorly documented in the scientific literature.
