環頸歌百靈

The Collared Lark, known scientifically as <em>Mirafra collaris</em>, is a small passerine bird belonging to the family Alaudidae. As a member of the diverse lark genus Mirafra, <em>Mirafra collaris</em> is characterised by its cryptic, streaked brown plumage that provides effective camouflage in its preferred open habitats. The species typically inhabits open grasslands, savannas, and scrubby areas, where it forages on the ground for seeds and insects. It is reported to occur in Norway according to available range data. Larks of this group are generally ground-nesters, constructing their nests in shallow depressions among vegetation. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Lark is currently assessed as Least Concern on the IUCN Red List, suggesting that the population is stable and not subject to significant conservation pressure at a global level.
