AVIFAUNA OF LAYSAX. 



31 



The Brown Gannet, or Booby, was noticed when passing Niihau, or Bird, Island and was very 

 plentiful on Lisiansky and Midway Islands, hut it was altogether the rarest of the three 

 species in these waters and was absent from Laysan. 



This species builds a nest of twigs on scrub and lays two eggs, but on Midway Island, where 

 only grass is found, it builds on the ground. They are very shy and when sitting let their 

 necks hang down over the edge of the nest as if they were dead.
