Perching duck
The term perching ducks is used colloquially to mean any
ducks distinguished by their readiness to perch high in trees
.
Until the late 20th century, perching ducks meant Cairinini, a
paraphyletic and their apparent similarity results from convergent evolution, with the different members more closely related to various other ducks than to each other.[1]
Perching duck species include:
Plectropterinae
- Spur-winged goose Plectropterus gambensis
- Salvadori's teal Salvadorina waigiuensis (initially placed in Anatinae)
- Blue duck Hymenolaimus malacorhynchos
- Torrent duck Merganetta armata
- Brazilian teal Amazonetta brasiliensis
