The great egret stands up to 1m tall and measures 80 to 104cm in length with a wingspan of 131 to 170cm. Body mass ranges from 700 to 1,500g, averaging about 1,000g (Wikipedia, general species account).
It breeds in colonies in trees close to large lakes with reed beds or other extensive wetlands, preferably at 3 to 12m up. The source read for the Bhutan guide gives these details only. No plumage, range or diet information was found, so none is stated, and its occurrence in Bhutan is flagged.
