Common stork's bill

<em>Erodium ciconium</em>, the common stork's-bill, is an annual or biennial flowering plant in the family Geraniaceae, order Geraniales. It is native to the Mediterranean region and southern Europe and has been introduced to parts of North America. The species typically inhabits dry, disturbed habitats including roadsides, cultivated fields, rocky slopes, and coastal areas, favoring sandy or calcareous soils with good drainage. Its pink to purple flowers are relatively small, and the distinctive elongated fruit resembles a stork's bill, a characteristic shared across the genus <em>Erodium</em>. The beak-like fruits are adapted for wind and animal dispersal, with hygroscopic awns that drill the seed into the soil through coiling movements in response to moisture changes. Biological traits such as typical lifespan duration, average biomass, and detailed dietary associations remain poorly documented at the species level. <em>Erodium ciconium</em> has not been formally evaluated by the IUCN, though it is generally considered a common species without significant conservation concern across most of its range.

Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
