LS # 21 (cont.) 
Boobies which left the ground and flew easily were seldom pursued by the 
frigatebirds, while those which appeared to have difficulty in taking 
flight were almost invariably pursued. 
Data on island of banding were available for 193 of the 204 Blue¬ 
faced Boobies returned. One-hundred seventy-one of the 193 ( 89 $) had 
been banded on Lisianski; the rest on other islands. Twelve of the 22 
( 55 $) interisland boobies were banded on Laysan; 4 ( 18 $) were banded on 
French Frigate Shoals; 3 (l4$) were banded on Pearl and Hermes; 2 ( 9 $) 
were banded on Kure; and 1 (5$) was banded on Johnston.
