New Zealand Shearwater 

 Puffinus bullerl Salvin 



Status : Possibly rare migrant. 



This species is included in the species ac- 

 count on the basis of three sight records--one 

 each in March 1964, March 1965, and April 

 1965--all of which must be considered tentative. 



POBSP personnel collected one specimen at 

 a comparable latitude west of the study area.

This species first appeared on March 19, 

 1964. The peak of the northward migration was 

 toward the end of March. A fairly heavy move- 

 ment was still underway through April, but by 

 the end of May the species had all but dis- 

 appeared from the study area. In 1965 the 

 northward migration lasted slightly longer. 

 Fairly large numbers were seen from March 

 19 through the end of May, although the greatest 

 densities were recorded between March 19 and 

 April 19. 



The southward migration started on Septem- 

 ber 16 and ran sporadically until the end of 

 November. The peak was in the first week of 

 October. 



Their behavior was typical of sea birds on 

 migration. Most birds traveled singly and 

 showed little inclination to feed or rest. In 

 spring the most frequently observed direction 

 of flight was northwest. In fall the direction 

 was due south.
