Mochuelo acollarado

The Collared Owlet, known scientifically as <em>Glaucidium brodiei</em>, is a small owl belonging to the family Strigidae. As one of the smallest owls in its range, <em>Glaucidium brodiei</em> is characterised by its compact body, rounded head without ear tufts, and distinctive false eyespots — dark patches on the back of the head that may serve as a deterrent against predators. The species typically inhabits montane and submontane forests, where it hunts insects, small birds, and other small vertebrates. It is reported to occur in Norway according to available range data. Collared Owlets are largely diurnal or crepuscular in behaviour, often calling from exposed perches. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Owlet is currently assessed as Least Concern on the IUCN Red List.
