LISXAN3KI 
The Gray-backed Tern nesting cycle on Lisianski was essentially 
finished with only a few starving chicks still remaining on the island. 
About five of these young were found in the northern interior near a group 
of nesting Red-footed Boobies and Great Frigatebirds. About five more 
young were found in a clearing at the southwest interior of the island 
near the area utilized for nesting by one of the small groups of Brown 
Boobies. Very few adults were seen. It seems likely that' most‘~of the‘ 7 “ 
young still on the Island have been abandoned by their parents*

to that occupied by the Sooty Terns.
