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.

Common Tailorbird

<em>Orthotomus sutorius</em>, the common tailorbird, is a small passerine in the family Cisticolidae, widely distributed across South and Southeast Asia. Despite one distribution record indicating Norway, the species is primarily a tropical and subtropical resident, inhabiting gardens, scrub, forest edges, and cultivated areas from India through Southeast Asia. It is classified as Least Concern on the IUCN Red List owing to its broad range and adaptability to human-altered landscapes. The common tailorbird is renowned for its remarkable nest construction: the female stitches large leaves together with plant fiber or spider silk to form a cradle in which the cup nest is built, giving the species its common name. It feeds primarily on insects and spiders gleaned from foliage and bark. The song is a loud, repetitive call frequently heard in gardens. Plumage is typically olive-green above with a rufous crown and pale underparts. Biological traits such as precise body weight, wingspan, and lifespan data remain poorly documented in comprehensive standardized assessments, though adults typically weigh between 6 and 10 grams.
