Figure 6b. — Distribution of Juan Fernandez and White-necked Petrels, October 1964 to January 1965. 



Usually only one bird was seen at a time, and 

 never more than two together. 



The migration peaks for this species were 

 similar to those of the Sooty Shearwater which 

 also breeds in New Zealand.
