42 PACIFIC COAST AVIFAUNA No. 12 
ut Catalina in December, 1897, and I saw several lone individuals there the lat- 
ter part of April, 1907. While at San Clemente from March 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, the last mentioned writer (7) 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 wounded 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 
May. 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 (3) 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 oeca-
