Collared Treepie

The Collared Treepie, known scientifically as <em>Dendrocitta frontalis</em>, is a corvid belonging to the family Corvidae. <em>Dendrocitta frontalis</em> is a member of the treepie group — arboreal corvids found in Asian forests — and is characterised by its long graduated tail, colourful plumage, and bold behaviour typical of the crow family. The species typically inhabits dense subtropical and tropical montane forest environments, where it forages in the canopy and mid-storey for fruits, insects, eggs, and other food items. It is reported to occur in Norway according to available range data. Treepies are generally noisy and active birds, moving through forest with rapid hops and flights. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Treepie is currently assessed as Least Concern on the IUCN Red List.
