The Masked Finfoot (Heliopais personata) is a specially adapted aquatic bird found across Southern Asia including Malaysia, Indochina and Indonesia.
The Masked Finfoot belongs to the Heliornithidae family, a small family of tropical birds with webbed lobes on their feet and includes the African Finfoot and the Sungrebe.
The Masked Finfoot is a shy and reserved bird, but quite tame particularly when incubating eggs which makes it vulnerable to human predatation.
Use the information below to find out more about the Masked Finfoot’s characteristics, habitat, diet, behaviour and reproduction.
Masked Finfoot Characteristics
The Masked Finfoot measures 52 – 54.5 centimetres (20.5 – 21.5 inches) in length. It has a curved neck and a sharp, thick, pointed orange/yellow beak. Males have a small horn at the base of the beak.
As its name suggests, both male and female finfoots have a black facial mask and eyebrow which contrasts with a white eyering and neck marking. The lower half of the neck is grey and it’s breast is pale grey. The back, tail and wings are a rich brown color. Males have a black chin while females have a white chin.
The finfoots legs and feet have yellow and black stripes and it has been speculated that, as these colors are not involved in any behavioural displays, they may be some kind of warning to underwater predators. Yellow and black stripes are one of natures classic deterrents as seen in wasps, caterpillars and snakes.
Masked Finfoot Habitat
The Masked Finfoot is adapted for a variety of aquatic habitats such as brackish wetlands, mangrove swamps and lowland riverine forests, as well as forests and savanna woodlands. It has been recorded in both coastal and inland wetlands, such as tidal creeks and flooded forests.
Masked Finfoot Diet
Finfoots will also take prey off the waters surface and being skilled out of the water as well as in, they will also forage on river banks.
Masked Finfoot Behaviour
Masked Finfoots are not gregarious birds and are only usually observed in pairs or singular. Although it is adapted for aquatic surroundings, it is quite competent on land.
The masked finfoot can run quite fast on land and even clamber into trees and is quite agile at manouevring through the branches. The reason why these birds are quite flexible on land is due to their feet not being fully webbed. Instead, their feet are lobed like in Grebes and Coots. This enables the finfoot to be competent in water by using its lobed feet to propel itself through the water and yet unrestricted on land.
Masked Finfoots are vocal birds and produce a rather high-pitched bubbling sound during courtship, sometimes followed by clucks.
Masked Finfoot Reproduction
The breeding habits of the Masked Finfoot are fairly unknown as it is such a secretive bird. They are so elusive that even experienced ornithologists do not fully understand their behaviour or if they spend more time in the water than on land.
It is thought that breeding coincides with the rainy seasons. Nests are a pad-shaped structure of small sticks that is constrcuted above the water. Females lay 5 – 7 eggs into the nests. Finfoot chicks leave the nest shortly after hatching. Life span is unknown.
Masked Finfoot Conservation Status
The Masked Finfoot is classed as ‘Endangered‘ and are still declining in numbers. This elusive species has a very small, and very rapidly declining population. Fewer than 2,500 birds are thought to populate the world. Threats include habitat loss and human disturbances. The Masked Finfoot is protected in Malaysia.
