Salvadorina waigiuensis
The enigmatic Salvadori's Teal (*Salvadorina waigiuensis*) is a unique, medium-sized duck endemic to the fast-flowing montane rivers and streams of New Guinea. Measuring approximately 43-48 cm (17-19 inches) in length and weighing around 580-680 grams, its appearance is distinctive, featuring a dark brown head and neck, a chestnut-brown breast, and flanks mottled with blackish-brown spots, contrasting with its black bill tipped with bright orange-yellow and equally vibrant orange-yellow legs ...
This species exclusively inhabits fast-flowing, clear-water montane rivers, streams, and occasionally high-altitude lakes within dense forest environments. It typically occurs at elevations ranging from 600 to 4000 meters, predominantly between 1500-3000 meters.
The diet consists mainly of aquatic invertebrates, including insect larvae (e.g., caddisflies, mayflies) and small crustaceans, supplemented with small fish, tadpoles, and some aquatic plant matter. It forages by dabbling, up-ending, and diving in swift currents to snatch prey.
Salvadori's Teal is primarily diurnal, actively foraging throughout the day along its specialized riverine habitat, often roosting on rocks or secluded riverbanks. Its foraging strategy is uniquely adapted to turbulent waters, involving dabbling, up-ending, and agile diving to capture aquatic pre...
