Collared Sparrowhawk

The Collared Sparrowhawk, known scientifically as <em>Accipiter cirrocephalus</em>, is a small bird of prey belonging to the family Accipitridae. As a member of the genus Accipiter, <em>Accipiter cirrocephalus</em> is characterised by its short, rounded wings and long tail, adaptations that enable agile manoeuvring through forest and woodland habitats while pursuing bird prey. The species typically inhabits forests, woodland, and forest edges, where it hunts small birds and occasionally insects. It is reported to occur in Norway according to available range data. Adult males of this species often display a distinctive rufous collar on the nape, which contributes to the species' common name. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sparrowhawk is currently assessed as Least Concern on the IUCN Red List.

Common White Heart-Leaf Aster

<em>Eurybia divaricata</em>, commonly known as the common white heart-leaf aster or white wood aster, is a perennial flowering plant in the family Asteraceae. Its conservation status is listed as Not Evaluated by the IUCN. The species is native to eastern North America and has also been recorded in parts of Europe, where it grows in shaded woodland environments, forest edges, and disturbed habitats with partial to deep shade. It typically flowers in late summer and autumn, producing numerous small white daisy-like flower heads with yellow centers that age to reddish-purple, creating a striking two-toned effect across a single flowering colony. The plant grows from a creeping rhizome and typically reaches 30–90 cm in height, forming loosely spreading colonies in suitable conditions. Leaves are heart-shaped at the base, providing the basis for the common name. <em>Eurybia divaricata</em> is considered a shade-tolerant woodland specialist that thrives in nutrient-poor soils under closed forest canopy, making it a useful indicator of relatively undisturbed eastern deciduous forest understory. Biological traits including average lifespan, precise height, and mass remain poorly documented in standardized databases. Ecologically, the white wood aster provides late-season nectar and pollen resources for pollinators including bees and butterflies at a time when few other woodland species are flowering, making it a valuable component of woodland biodiversity across its native and introduced range.
