The Indian roller is 30 to 34cm long with a wingspan of 65 to 74cm and weighs 166 to 176g. The female lays three to five eggs in a cavity or crevice lined with a thin mat of straw or feathers, and the fledging period lasts 30 to 35 days (Wikipedia, general species account).
The only source read for the Bhutan guide gives these measurements and nesting details. No plumage, range, habitat or diet information was found, so none is stated, and its occurrence in Bhutan is flagged for checking.
