The Collared Redstart, known scientifically as <em>Myioborus torquatus</em>, is a small passerine bird belonging to the family Parulidae, the New World warblers. <em>Myioborus torquatus</em> is a member of the whitestart or redstart group, known for their habit of fanning or spreading their tail feathers to startle insects from vegetation. The Collared Redstart is typically characterised by bright, contrasting plumage, including a distinctive collar pattern and vivid colouration on the head and underparts. The species inhabits montane forests and forest edges at higher elevations, where it is often observed foraging actively through the understorey and mid-canopy. 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 Redstart is currently assessed as Least Concern on the IUCN Red List.
