Bext to the Sooty Tern this was the most abundant speciqs on the island. 
The majority of birds were in the process, of nesting, “^arrows were 
located in all types of cover, but were especially numerous in the bunch- 
grass associations. This type of area,also coincided with large portions 
of the Sooty Tern colonies. The burrows practically undermine certain parts 
of this cover.
