Young birds were found just breaking the shell December 4. They 

 are hatched much earlier when the rookeries are not so often robbed : 

 as early as October 12, certainly. When first hatched, the young are 

 covered with soft, hairy, pearl-gray down. Head black above and 

 behind ; bill flesh-colored ; feet black on the soles and flesh- colored 

 above.

Begins to lay about the first of December, building among fallen 

 rocks by the sea, making nests which are more complete than those of 

 Pygoscelis twniata, and lining them with dried grass. There are two 

 eggs to a nest, white, with a faint tiuge of greenish, obtusely ovoid in 

 shape, and usually one is distinctly larger than the other. The shells 

 are thick, friable, inelastic, and often smeared in parts with calca- 

 reous deposit. The external surface is punctured by minute pores, 

 scattered widely apart, but presents no distinct surface-marking.
