Disappearing ducks: Madagascar teal

There are only 1,500 Madagascar teal living in the wild. They look similar to a female Mallard found in the UK (Anas platyrhynchos), but are instead threatened with extinction. They were once one of the island’s most common inhabitants.

Less forest, less shrimp, less teal

The population of Madagascar teal has fallen rapidly due to habitat destruction of their preferred mangrove forests. Teal rely on these flooded swamps for invertebrates and plant material found in the water.

The forests are cut down for timber, fuel, and to create flooded (paddy) fields for cultivating rice, a nationally important crop. This habitat loss has, in turn, reduced the shrimp population that depends on the forests as ‘nursery beds’.

Shrimp are another nationally important crop and with smaller harvests, islanders are now hunting the Madagascar teal as an alternative food source. Unfortunately, the teal are calm around humans and fairly easy to catch.

An international conservation project is now trying to protect these endangered ducks, involving the Madagascar Government and overseas partners such as the Durrell Wildlife Conservation Trust in Jersey. The Living Rainforest has two protected Madagascar teal which can often be seen walking around our Amazonica House.

Nesting in trees

Madagascar teals make their nest in tree cavities up to 5m high (16’). But this means the hatchlings have to fall from this height to leave the nest. Luckily, the youngsters are cushioned by a flexible cartilage, a ‘bouncy’ connective tissue that protects the chick before the bones have fully formed.

The ducklings are further protected by fiercely territorial parents who live away from other teal during breeding. The breeding pair nurse clutches of up to six eggs laid during the wet season early in the year. These eggs hatch within four weeks and the ducklings grow plumage after another six.

Look out for…

Two pairs of ringed teal (Callonetta leucophrys) that also live at The Living Rainforest. These colourful relatives are native to large stretches of rainforest in South America, including north-west Argentina, Paraguay, Bolivia, Uruguay, and Brazil.

    I’m a realistic decoy (duck) carver who is actually writing a book on world teals. I would like to have information about Madagascar Teal ; if this species is protected, I imagine that it never has been hunted. As, in my book, I’ll introduce teals as living birds and also in their artistic evolution as wooden ducks, is it possible to get in touch with some persons having created artificial artistic teal, even as hunting decoy or decorative decoy. I can give you further information, if needed. Also, as my native language is French, I can communicate in both languages.
