The eggs of the Golden-crowned Water-Thrush are of a very broad 
and blunt oval shape and but very slightly glossy. They are white, 
spotted and blotched, more densely at the broad end where the 
markings are more or less confluent and form a cap, with pale rufous, 
reddish-brown, lilac-red and purplish-grey, all these colours being 
usually combined on one egg. They measure from °78 to *85 in 
length, and from 6 to °65 in breadth.
