88 PACIFIC COAST AVIFAUNA No. 12 
TIuey (ZS) noted two or three birds about the caves of San Clemente in April, 
1915, and G. Willett (JZS) says he saw them building commonly in the eaves of 
Catalina during April, 1904. H. Wright (9) saw birds on Santa Barbara Isl- 
and, July 2 and 3, 1912, and he found a nest with an addled ege on Anacapa, 
July 1. Abundant on Santa Cruz, where, in April, 1911, we found them nesting 
in a certain large tide cave in such numbers that their twittering could be heard 
a long distance away. They frequently visited a spring near camp for the pur- 
pose of gathering mud, sometimes trailing long wisps of grass in their wakes.
