THE nest of the Skua is of large size, as well as somewhat carefully 

 constructed; the materials used being grass, lichens, moss, and heath. 

 The bird places it on the tops of the mountains or cliffs in the neigh- 

 bourhood of the sea, but not on the rocks themselves. They build 

 separately in pairs. 



The eggs are only two. They are laid towards the end of June.
