TO MR. C. IRVIN CLAY, of Eureka, belongs the honor of first 

 discovery of the Fork-tailed Petrel as a breeding bird of California. In 

 one of those privileged hours which are sometimes allotted to good bird- 

 men, Clay had ransacked Whaler Island, in the harbor of Crescent City, 

 and discovered Fork-tails breeding in some numbers. He secured eight 

 eggs, of which five are now in the Museum of Comparative Oology, and 

 skins of two parents. The date, May 14, 1916, was decidedly early in 

 comparison with the nesting dates of 0. 1, beali.
