The eggs of the Petrels are white, frequently tinged, when fresh 

 and clean, with very pale blue. Those of many species are without 

 markings of any kind ; in those of others one end is speckled and 

 spotted with rufous so as to form a cap or zone, and the markings 

 often extend over a considerable portion of the shell. They are 

 usually without gloss, and in no case is there more than a very slight 

 amount of this. The sheU is, as a rule, slightly rough and somewhat 

 chalky, but the eggs of some species are fairly smooth. They vary 

 much in shape.
