Pacific Golden Plover

The Pacific golden plover is about 25cm long with a wingspan averaging 61cm. At its lightest, with no fat, a bird weighs around 135g. From March the birds begin gaining weight, and before leaving for their Arctic breeding grounds they weigh about 200g (Wikipedia, general species account).

The moult into non-breeding plumage begins in the Arctic during egg incubation. The source read for the Bhutan guide gives these measurements and the moult only. No plumage description, range, habitat or diet information was found, so none is stated.
