Prinia hodgsonii
Clutch size
Typically 3–4 eggs, glossy blue, pinkish white, greenish blue or pure white
Incubation period
Both parents; hatch after about 10–11 days
The typical clutch of the grey-breasted prinia is three or four eggs. The eggs vary in colour, from glossy blue to pinkish white, greenish blue or even pure white. Both parents incubate them, and they hatch after about ten to eleven days (Wikipedia, general species account).
That is all the source read for the Bhutan guide gives. No plumage, size, range, habitat or diet information was found, so none is stated, and its occurrence in Bhutan is flagged for checking.
