The eggs of the Yellow-headed Troupial are mostly of an 

 elongate oval shape and fairly glossy. They vary from greyish- 

 white to greenish-white, and are densely speckled and mottled 

 with various shades of brown, grey, and pale rufous. The markings 

 are most dense on the broad end of the egg, but seldom form a 

 conspicuous cap. Numerous specimens measure from 1 to 1*2 in 

 length, and from "7 to -78 in breadth.

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 : I'Ol by '73 ; 1 by -73 ; 

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

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

 describes the ground-colour as yellowish-white.
