Bengal Florican: The Grassland Bustard on the Brink

A grassland bird almost no one sees

The Bengal Florican (Houbaropsis bengalensis) is a small, secretive bustard of tall grassland. Males are jet black with contrasting white wing patches; females are cryptic, buff and streaked. Both are hard to see except in the brief display season, when males leap vertically above the grass.

With fewer than 1,000 mature birds across its entire global range, the species is one of the rarest bustards on Earth, and possibly the rarest.

Two populations, one problem

There are two disjunct populations. The northern population lives along the Terai — a belt of tall alluvial grassland at the foot of the Himalayas — from Uttar Pradesh through Nepal, Bhutan and Assam. The southern population lives on the seasonally flooded grasslands around Cambodia's Tonle Sap lake.

Both populations depend on tall (>1 m) grassland with a mosaic of shorter patches for display. Both types of grassland are among the most heavily converted habitats in Asia — to agriculture, dry-season rice, plantations, and settlements.

The extraordinary leap display

In March–May, male Bengal Floricans perform one of the most theatrical displays in the bird world. From a small patch of shorter grass, a male leaps 2–3 metres straight up, hangs for a second with wings whirring, and drops back down. He repeats this every few minutes at dawn and dusk.

The display advertises the male to females at long range across the flat grassland — a signal that only works if the grassland stays open and unfragmented.

Why the numbers keep falling

The main threat is grassland conversion. In the Terai, cattle grazing pressure and shrub encroachment have degraded the tall-grass mosaic; in Cambodia, more than 50% of Bengal Florican habitat around Tonle Sap has been converted to dry-season rice in the last two decades.

Additional threats include electrocution and collision with power lines, egg collection, and — in Cambodia — direct hunting for meat and the pet trade.

Community-managed grasslands

In Cambodia, a network of Bengal Florican Conservation Areas covering more than 300 km² was established from 2006 onwards, in partnership with local communities. Landowners are paid annual incentives to leave grassland unploughed during the breeding season.

In India, key sites include Manas National Park, Kaziranga, and Dudhwa; Nepal's Shuklaphanta and Chitwan National Parks hold the largest remaining northern population. Coordinated tall-grass burning and grazing regimes are being tested in several of these reserves.

A bustard worth stopping for

The Bengal Florican is small, secretive, and easy to overlook — which is exactly why its grassland has been treated as wasteland. Saving it means treating Asian tall grasslands as a globally important habitat in their own right, not merely land waiting to be ploughed.
