E. Z. Rett (1947) comments that San Nicolas Island, some 70 miles 

 due south of Carpinteria, Santa Barbara County, Calif., and the most 

 distant offshore of the Channel Islands, is a stopping place for anthi- 

 nus in the spring and fall migrations. 



Chester C. Lamb's (1929) comments on a 15 day cruise in September 

 from San Francisco to La Paz in lower California are of interest: "The 

 steamer kept at a distance of from 8 to 20 miles offshore most of the 

 way. The weather was windless and the sea calm the whole distance. 

 Among the many species of birds which came aboard were two Savan- 

 nah sparrows, which he identified as alandinus (now anthintts). He 

 went on deck at 6:00 a.m. on September 26 and observed these birds 

 hopping around the deck cargo. The steamer was about 10 miles off 

 San Antonio del Mar. These birds were not seen after 10:00 a.m. 

 On September 28, off Magdelena Bay, at 8:00 a.m. another came 

 aboard but remained only two hours."
