About These Birds
European Nightjar
A medium Caprimulgidae nightjar (~76 g) breeding across Eurasia from Britain to central Siberia in open heath, scrub, and pine plantations. Males produce a sustained mechanical churring song at dusk. Long-distance migrant wintering in sub-Saharan Africa. Feeds on moths and beetles. Least Concern despite local heathland declines.
Archbold's Nightjar
A small Caprimulgidae nightjar (~77 g) known from subalpine grasslands and forest margins in the interior mountains of New Guinea. Named after naturalist Richard Archbold. Cryptic brown-patterned plumage. Nocturnal insectivore. Infrequently observed; biology largely undescribed. Least Concern in its montane range.
