Esacus recurvirostris
Habitat
Bare scrape on open shingle
Clutch size
A single egg
Size
49–55cm; bill about 7cm
The great stone-curlew, or great thick-knee, is a large wader of 49 to 55cm with a massive 7cm bill whose lower mandible has a sharp angle that gives it an upturned look. A single egg is laid in a bare scrape on open shingle (Wikipedia, general species account).
The source read for the Bhutan guide gives these details and nothing else. No plumage, range or diet information was found, so none is stated, and its occurrence in Bhutan is flagged for checking.
