Torrent Duck vs Crested Duck: common questions
Which one is specialised for fast-flowing rivers?
The torrent duck is specialised this way, with a streamlined, muscular body built to swim against powerful currents, a habitat the crested duck does not specifically depend on.
Which one has a distinctive head crest?
The crested duck has this feature, a shaggy tuft of feathers on the back of its head, a trait not shared by the torrent duck.
Which one ranges across the broader elevation span?
The crested duck ranges more broadly across elevation, found from sea-level coastlines to high Andean lakes, while the torrent duck instead stays tied specifically to fast-flowing river habitat.
