Collared Laughingthrush

The Collared Laughingthrush, known scientifically as <em>Trochalopteron yersini</em>, is a passerine bird belonging to the family Leiothrichidae, a group commonly known as laughingthrushes. <em>Trochalopteron yersini</em> is characterised by its rich, colourful plumage, typically featuring rufous, grey, and black tones with a distinctive collar pattern. The species inhabits montane forests and forest edges, generally at higher elevations where dense understorey vegetation provides both foraging opportunities and cover. It is reported to occur in Norway according to available range data. Laughingthrushes are typically vocal and often move in small social flocks through the forest interior. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Laughingthrush is currently assessed as Endangered on the IUCN Red List, reflecting serious concerns about population decline, likely driven by habitat loss and degradation within its restricted range.

Comet Darner

<em>Anax longipes</em>, the comet darner, is a large dragonfly in the family Aeshnidae, assessed as Least Concern on the IUCN Red List. It is endemic to the United States, where it inhabits lakes, ponds, and slow-moving rivers with clear water and abundant emergent vegetation. The comet darner is one of the largest North American dragonflies and is distinguished by its brilliant coloration, including a green thorax and a red-spotted abdomen in mature males. The species name longipes refers to its notably long legs. Adults are powerful aerial predators, feeding on a variety of flying insects captured in flight. Larvae are aquatic and predatory, developing in the benthic zone of freshwater habitats where they feed on invertebrates and small vertebrates. The comet darner undertakes seasonal dispersal movements and is most commonly observed near its breeding water bodies during the warmer months.
