Description
The Mekong wagtail most closely resembles African pied wagtail M. aguimp, although two species ranges are far apart. It differs from M. agiump in several minor respects, particularly wing pattern, and its vocalisations are very distinctive. It is a very distinctive species and is the only black-and-white wagtail in South-East Asia which exhibits the plumage character combination of black forehead, lores and ear coverts, obvious white supercilia, with white a throat and neck patch.
Size
18 cm
Feeding Habits
Mekong Wagtail predominantly consumes small arthropods. It forages atop emergent bushes, walking on branches and picking food from foliage. Specific foraging behaviors outside breeding season remain undisclosed.
Habitat
Mekong Wagtail predominantly inhabits broad lowland river channels, specifically within regions where rivers exhibit braided patterns and swift-flowing waters. Their preferred environment displays a unique channel mosaic comprising sandbars, gravel shoals, emergent rocks, and specialized bushes like Homonoia riparia, which can withstand seasonal submersion. During the rainy season, when river levels rise and landscapes flood, mekong Wagtail adapts by favoring earthen banks and overhanging vegetation, as well as exposed sand and silt areas. They are typically found in pairs or small flocks in rivers exceeding 100 meters in width, often avoiding more exposed locations and higher vegetated islands similar to the adjacent floodplains.
Dite type
Insectivorous
General Info
Distribution Area
The Mekong River breeding in Cambodia and Laos, but apparently it is a non breeding visitor to Thailand. It also occurs in Vietnam.
Species Status
The Mekong wagtail is very tolerant of human presence, and its habitat is not very susceptible to human-induced changes. Damming proposals along the Mekong, in particular those on sections where the river has a low gradient, have the potential to destroy significant stretches of its riverine range by inundating the river channel
