coast amaranth

Coast amaranth (Amaranthus pumilus) is an annual herb in the family Amaranthaceae, native to the Atlantic and Gulf coasts of the eastern United States, where it once grew on coastal foredunes, beach strand, and shell-hash substrates above the high tide line from New York south to South Carolina. It is a low-growing, fleshy plant with small, rounded leaves and inconspicuous green flowers typical of the genus. Coast amaranth is assessed as Extinct in the Wild by the IUCN, as it has not been reliably documented from wild populations since the mid-20th century; the last confirmed collections date to the 1960s. The species' decline and likely extinction resulted from intense human pressure on Atlantic coastal habitats through shoreline development, beach stabilisation, vehicular traffic on beaches, and increased storm frequency disrupting pioneer dune vegetation. It is federally listed as Threatened in the United States, though this listing predates confirmed extinction in the wild. A small number of ex-situ accessions may exist in botanical garden collections. Genetic material and seed banking efforts represent the only remaining conservation options for this critically reduced species.

Зеленоголовая короткохвостая нектарница

The Collared Sunbird, known scientifically as <em>Hedydipna collaris</em>, is a small passerine bird belonging to the family Nectariniidae, the sunbirds. <em>Hedydipna collaris</em> is characterised by its iridescent plumage, with males typically displaying vibrant metallic green upperparts and a bright yellow belly separated by a purple collar band — a feature central to the species' common and scientific names. The species is primarily nectarivorous, feeding on nectar from flowering plants using its curved bill and brush-tipped tongue, and also consuming insects for protein. It inhabits forest edges, gardens, wooded savanna, and secondary vegetation across its range. It is reported to occur in Norway according to available range data. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sunbird is currently assessed as Least Concern on the IUCN Red List.
