The grey wagtail is a member of the wagtail family, about 18 to 19cm long overall. The clutch consists of three to six speckled eggs, and multiple broods may be raised, with declining numbers in the clutch in subsequent broods (Wikipedia, general species account).
The incubation period is about two weeks, with chicks fledging within a fortnight, and birds live for a maximum of eight years in the wild. The source read gives no range, habitat or diet information, and does not name Bhutan, so none is stated.
