Eggs of the Scarlet-headed Marsh-bird are of an ordinary oval 

 shape and glossy. They closely resemble eggs of the Common 

 Song-Thrush, the ground being pale blue, sparingly marked with 

 a few small spots and irregular marks of dark purplish-black and 

 purplish-grey. They measure respectively : 1-01 by -73 ; 1 by -73 ; 

 1 by -72 ; -98 by -74. These eggs agree with the description giveu 

 by Hudson, but not with that given by Eurmeister. Nehrkorn 

 describes the ground-colour as yellowish-while.
