Tringa ochropus
Habitat
Lays in an old tree nest of another species
Clutch size
2–4 eggs
Incubation period
About three weeks
The green sandpiper lays two to four eggs in an old tree nest of another species, such as a fieldfare's. The clutch takes about three weeks to hatch (Wikipedia, general species account).
The only source read for the Bhutan guide gives this unusual nesting habit and nothing else. No plumage, size, range, diet or habitat information was found, so none is stated, and the entry is kept short.
