various kinds, and a few horsehairs. 

 Seaweed is not always present in the 

 structure, and horsehair frequently ab- 

 sent when the bird is breeding on small 

 islands where it is not procurable. 



The eggs number from four to five, and 

 have a grey ground colour slightly tinged 

 with green or reddish-brown, closely 

 spotted with dull greyish- and reddish- 

 brown. They are occasionally marked 

 on the larger end with one or two dark 

 brown lines, and are larger than those 

 of the other two members of the family 

 breeding in our islands.
