Population estimate

Returned - 
c. 15000 
197 (adults)

Sooty Terns were nesting throughout much of the east-central interior 
of the island, particularly in sand- Eragrost1s associations hut also in 
areas where Ipomea had covered the ground. Most of the birds were with 
large chicks but a very few of the young were flying. A comparison of 
the stage of nesting on Lisianski with that on Pearl and Hermes suggests 
that the Lisianski population is about two weeks behind the one on Pearl 
and Hermes. 
Six of the 13 returns (46$) for which we knew the island of banding 
were banded on other islands. Two were banded on Laysan, and one each was 
banded on French Frigate Shoals,' Oahuy and Johnston. We have no explanation 
for this anomalously large proportion of interisland birds.

Sooty Terns were swirling over the north-central portion of the island 
and some were down on the ground. Kenyon investigated this area on the
