1965 



The Mottled Petrel first appeared on October 

 13, 1964. Peak numbers--22 birds--were seen 

 on October 18, 1964. Only two were seen in 

 November and two in December. All of these 

 records were of birds heading south, flying in a 

 manner that clearly suggested a direct migra- 

 tion. Several birds were in the company of mi- 

 grating Sooty Shearwaters. 



The return migration from New Zealand, 

 where the species breeds during the Southern 

 Hemisphere summer, was not as strong. Only 

 11 birds were seen, 10 in April 1965. The spe- 

 cies was probably overlooked in 1964. POBSP 

 has several specimen records for the central 

 Pacific. 



The distribution showed no particular pattern 

 in the study area. Birds were seen from lat. 

 11° to 25° N. and from long. 148° to 157° W., 

 indicating that they migrated along a broad 

 front.
