BUDDY TUBNSTONE 489 



Being restricted in its occurrence in California, both as to season 

 and locality, and with a breeding ground so sequestered as to have 

 completely eluded man's search, the Surf -bird seldom comes under 

 the surveillance of our sportsmen. It is safe to say that it will never 

 be a species of importance among the game birds of the state. It is, 

 nevertheless, a noteworthy member of our bird fauna. As Torrey 

 (1913, p. 138) has aptly said with reference to its unknown nesting 

 habits, "somehow it is impossible not to feel a certain heightened 

 respect for birds that have succeeded in keeping such a secret in 

 despite of man's insatiable curiosity."
