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.

Collared Warbling-Finch

The Collared Warbling Finch, known scientifically as <em>Poospiza hispaniolensis</em>, is a small passerine bird belonging to the family Thraupidae, the tanagers and allies. <em>Poospiza hispaniolensis</em> is characterised by its neatly patterned plumage, which typically features contrasting black-and-white head markings and a distinctive collar or chest band element consistent with other members of the warbling finch group. The species typically inhabits scrubby, arid, and semi-arid environments, foraging for seeds and small invertebrates in low vegetation and on the ground. It is reported to occur in Ecuador and Norway. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Warbling Finch is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is stable without significant conservation concerns.
