L Sff 19 (cont. ) were being constructed^ I would estimated that only 50 percent of 
the pairs had nests. There were up to 5*000 nests on the island wid when 
nesting is completed there will be up to 7 , 000 nests or young raised for the 
year, -j 
I conducted two studies on Common Noddy nests; the data are included in 
two tables. In the first study I recorded all the live plants withing 
three feet of the nest site. Scaevola was the most comon plant associated 
with nests and then Eragrostis and Ipomea. When comparing data from this 
Island with data from Laysan and Pearl a nd Hermes, it is evident which 
plants are .most closely associated with, nestng on a particular island. 
In the other study I recorded all materials used in the nest by species. 
The data collected in both studies should be slef-explanatory and easily 
comparied with data from otherislads.

(FCT) Total population estimate; 10,000. The Common Noddies were mainly 
in the Scaevola band aro 8 nd the island: most on eggs — no chicks seen. 
No differences were noted in mode of nest building.
