Editing Perching duck

{{Short description|Colloquial term for ducks that perch in trees}}
The term '''perching ducks''' is used colloquially to mean any [[species]] of [[ducks]] distinguished by their readiness to perch high in [[tree]]s.

Until the late 20th century, '''perching ducks''' meant ''Cairinini'', a [[Tribe (biology)|tribe]] of ducks in the [[duck]], [[goose]] and [[swan]] family [[Anatidae]], grouped together on the basis of their readiness to perch high in [[tree]]s. It has been subsequently shown that the grouping is [[paraphyletic]] and their apparent similarity results from [[convergent evolution]], with the different members more closely related to various other ducks than to each other.<ref name=Livezey/>

Perching duck species include: 

'''[[Plectropterinae]]'''
*[[Spur-winged goose]] ''Plectropterus gambensis''

'''[[Tadorninae]]'''
*[[Salvadori's teal]] ''Salvadorina waigiuensis'' (initially placed in Anatinae)
*[[Blue duck]] ''Hymenolaimus malacorhynchos''
*[[Torrent duck]] ''Merganetta armata''

'''[[Anatinae]]'''
*[[Brazilian teal]] ''Amazonetta brasiliensis''

Species that were formerly in the Cairinini tribe,  and do not have an identified current subfamily include:<ref name=Livezey/><ref name=Sraml/><ref name=Johnson/>
