42 PACIFIC COAST AVIFAUNA No. 12 



at Catalina in December, 1897, and I saw several lone individuals there the lat- 

 ter part of April, 1907. While at San Clemente from I\larch 23 to April 11, 1915, 

 I saw a single individual almost daily, and C. B. Linton (3) has noted the species 

 there as late as May 3, 1909. During November and December, 1907, at Santa 

 Cruz Island, tlie last mentioned writer (i) frequently saw it feeding among 

 the tide pools. 



44. Dafila acuta (Linnaeus) 



Pintail 



While in camp on San Clemente, April 4, 1915, a female of this species flew 

 close over D. R. Dickey and myself. She acted in a peculiar way, circling about 

 over the camp, and then flying high up the hillside along the shore. We judged 

 that she was a Avounded bird that had made her way to the island.

Abundant in winter about the islands, a few non-breeders remaining all 

 summer. The majority arrive the latter part of September and remain until 

 i\Iay. F. Stephens {2) found it common at Catalina the latter part of March, 

 1893, and I have seen it repeatedly there during April. G. Willett (.5) saw sev- 

 eral at Santa Cruz Island during November, 1907, and (5) found immatures 

 common at San Miguel, the middle of June, 1910.

Most numerous one of the genus, remaining with us all winter, and an occa- 

 sional non-breeder spending the summer. C. B. Linton (J) saw several at Cle- 

 mente during the winter of 1908, and D. R. Dickey and T saw a flock of five
