Collared Myna

The Collared Myna, known scientifically as <em>Acridotheres albocinctus</em>, is a passerine bird belonging to the starling family Sturnidae. <em>Acridotheres albocinctus</em> is recognised by its contrasting plumage, which typically features a dark body with a distinct white collar or band — a feature reflected in both its common and scientific names. As a member of the myna genus Acridotheres, this species generally inhabits open woodland, grassland edges, and areas associated with human settlement, where it forages on the ground for invertebrates, fruits, and seeds. 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 Myna is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is considered stable without significant conservation concerns at this time.

Common Button Lichen

<em>Buellia erubescens</em>, commonly known as the common button lichen, is a lichen species with documented occurrences across Asia, Europe, and North America, including countries such as Norway, Portugal, Sweden, Taiwan, and the United States. It typically colonizes diverse terrestrial surfaces, often found on bark, rock, or other substrates in temperate and boreal environments. Common button lichen belongs to the genus <em>Buellia</em> within the family Caliciaceae. As a crustose lichen, it typically forms tightly adhered, crust-like thalli on the surfaces it colonizes, making it characteristic of stable, undisturbed substrates. Biological traits such as average lifespan, thallus size, and biomass of this species remain poorly documented in the scientific literature. The species has not yet been formally evaluated by the IUCN, and its global conservation status therefore remains undetermined. Its occurrence across multiple continents suggests a wide ecological tolerance, though detailed population data and trend assessments are currently lacking for this taxon.
