7. Bengal Florican

Houbaropsis bengalensis

About

This otherwise reclusive bird is best known for its elaborate courtship display, where the male’s black and white plumage is shown off to good effect in short arching display flights, as well as choreographed strutting – with fluffed up neck feathers and a head pumping action, to attract females.

Bengal Florican is the only member of its genus Houbaropsis, and is the rarest member of the Bustard Order, Ortidiformes. Two thirds of the global population breed in the floodplain of the Tonle Sap Lake, Cambodia; they migrate up to 100km annually to escape the floodwaters in the non-breeding season. Thousands of kilometres away in Nepal and India, there exists another population of the same species which occupies the duars and terai grasslands along the base of the Himalayas. Both populations are in decline and threatened by habitat loss through drainage, conversion to agricultural land and plantations, the invasion of alien species, and damn construction. They are, or were, targeted by hunters for sport and food, leading to their decline.

Distribution

There are two populations of Bengal Florican, separated by thousands of kilometres. The western population is found in the Indian Subcontinent; birds here occupy a thin, patchy strip of relict habitat. The larger population is centred in Cambodia, concentrated in the floodplain grasslands that surround the Tonle Sap Lake. A very small number of individuals probably still breed in adjacent areas of Vietnam.

Habitat and Ecology

This species inhabit the short plains of subtropical riverine grassland, though they breed on grasslands towards the end of the dry season and undertake a short migration to low statue open forest. They are omnivores, feeding on insects, as well as seeds, fruits and flowers, and have been known to eat small lizards and snakes. They are very reclusive except in March-May when males competitively display in groups of at least seven birds, widely spaced.

Conservation Actions

For each key category of conservation action, we calculated a conservation attention score based on expert information. In this graph, a higher score means the action is being carried out more intensively over more of the species range. The colour shows how important each action is considered to be for the conservation of this species.

Overall Conservation Attention

We combined all of the expert information on conservation actions to calculate an overall conservation attention score for this species. Please help us to reach our goal of establishing dedicated conservation attention at “High” levels for all EDGE species.

More information

Recent studies have grouped all possible conservation activities for any species into nine key categories (Washington et. al 2015). For each action, we asked experts for each species to assess the extent to which that action is being carried out and how much of the species’ range that action occurs in. For each action we used these two pieces of information to calculate the conservation attention score per action. A score of 100 means that the action is being carried out to a high level across at least 75% of the species range. We then combined the scores for all actions into an overall conservation attention score for the species. The experts also judged how important each category was to the conservation of that particular species.

This wordcloud illustrates the threats facing this species. The size of each word indicates the extent of a species range that is affected by that threat (larger size means a greater area is affected). The colour of the word indicates how much that threat impacts the species (darker shades of red mean the threat is more severe).
