ANTARCTIC PETREL. 
One or two were caught on threads and landed. We finally saw the last of 
them on the day that we crossed the Antarctic Circle coming north. 
I have mentioned that between June 22nd and July 4th this bird was 
seen in considerable numbers every day in the South Pacific Ocean. This 
throws some light upon their movements during the winter and extends their 
range. They are not so strictly ice birds as they were supposed to be, since 
they leave the ice for the open ocean in the winter months.
