Eggs of the Yellow Warbler, or Summer Yellow-bird, are of a 
pointed oval shape and moderately glossy. They are. greenish- 
white, spotted and blotched with two or more shades of brown and 
light purple or slaty-grey. ‘The markings are sparse on the smaller 
half of the egg, but dense on the larger, where they often form a 
cap or a broad irregular zone. On two specimens in the Collection 
they are confined to a broad belt round the middle of the egg. 
Examples measure from *62 to 71 in length, and from °48 to °52 
in breadth.
