Collared Crescentchest

<em>Melanopareia torquata</em>, the Collared Crescentchest, is a bird in the family Melanopareiidae. This species is assessed as Least Concern on the IUCN Red List. It is native to South America, with its range extending through central Brazil, Bolivia, Paraguay, and Argentina, where it inhabits open dry habitats including cerrado scrubland, grasslands with scattered shrubs, and savanna. The crescentchests, family Melanopareiidae, are a small group of ground-dwelling birds that creep through dense vegetation and are often difficult to observe. The Collared Crescentchest is named for the distinctive dark crescent marking across the breast. Diet information typically includes insects and other invertebrates, though specific data for this species are not enumerated in the available records. Biological measurements such as average length, weight, and lifespan are not specified in available data. Biological traits of this species remain poorly documented in the scientific literature. The species is associated with aerial, terrestrial, and aquatic environments within its range. Its Least Concern status reflects stable populations in South American savanna habitats.

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.
