The eggs of the American Redstart are mostly of a pointed oval 
form and exhibit a small amount of gloss. They are somewhat 
similar to the eggs of Dendreca westiva, but the ground-colour is 
generally white, instead of greenish-white, and the brown markings 
have usually a decided rufous tinge. Specimens measure from °6 to 
‘7 in length, and from 48 to ‘52 in breadth.
