blue whale

O maior animal que já viveu na Terra, as baleias-azuis podem atingir 33 metros e 200 toneladas — seus corações sozinhos pesam tanto quanto um carro pequeno. Encontradas em todos os oceanos, migram entre áreas de alimentação polares e áreas de reprodução tropicais. Filtradores que consomem até 4 toneladas de krill diariamente. Em perigo, com populações globais estimadas em 10.000–25.000 após a quase extinção causada pela caça baleeira no século XX.

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.
