One of the most interesting finds -.-.-as an all black storm petrel, possibly 
a dark phase of the VJhite-throated Storm Petrel, If so, this would bo the 
second soeeies for which a dark phase has been found on this island and which 
has not bean previously reported in the Literature* 
23 hours were spent* ashore 
oh birds were observed oh which four were breeding (an increase of 3 dn one 
Baker Island 
here carrying out the survey work. 12 species 
•■'TV' - AT 
*. i v-i:- W 
breeding species over previous trips). 214 birds of three species 
were banded with 15 returns recorded* The absence of cats seens to be the 
factor responsible for the increase inbird numbers and also for the increase 
in the nouse population. The presence of nice had been previously ienown only 
from the remains found in a cat stomach. On this trip an lost every board had 
0 . mouse hiding under it*
