A negligible decrease from 19 birds in January to 15 in February 
was recorded. The species tended to have a more northerly distribution 
this month. 
Sooty Tern 
A 54°/o decrease from 2554 in January to 179^ in February may 
possibly be of significance. As in previous months greatest concentrations 
were observed in the southeastern corner and around the high Hawaiian 
Islands. Except in these two areas, fewer larger flocks vere recorded. 
Many immature birds were seen in the south, but all northern birds 
were adults.

over 100 miles south of Oahu. The remainder were seen within sight of 
Oahu.
