50 NESTS AND EGGS OF 



86a. Lesser Fulmar. 



This subspecies occurs as far north on the American side as the coast of New 

 England. It is a smaller race than the typical F. glacialis. 



86b. PACIFIC PTILMAB. Fulmarns glacialis fflupischa (Stejn.) Geog. Dist. — 

 North Pacific, south on the American coast to Mexico. * 



This race is also known in light and dark phases of plumage. Dr. Leonhard 

 Stejneger found it breeding in enormous numbers in suitable places on the islands 

 in Bering Sea off the coast of Kamtschatka. Their rookeries were in high and steep 

 rocky bluffs and promontories, rising out of the sea 300 to 800 feet. Dr. Stejneger 

 says: "I have spent hours under their rookeries listening to their whining voice and 

 watching their high and elegant flight in sailing out and in and around the cracked, 

 rocks, like bees at an immense bee-hive." The egg is single and pure white. Five 

 eggs collected on Copper Island, July 12th and 13th, exhibit the following dimen- 

 sions: 75 by 49, 71.5 by 48.5, 71.5 by 51, 68 by 50, 71.5 by 48.5 mm.* These eggs all 

 belonged to the dark phase of birds. 



86c. BOBGER'S FTJLMAIl. Fulmarns glacialis rodgersii (Cass.) Geog. Dist. — 

 Bering Sea. 



Rodger's Fulmar is similar to the preceding, but there is no dark phase known. 

 Mr. Nelson says: "All of the Bering Sea Islands situated off shore and north of the 

 Aleutian chain are frequented by these Fulmars during the breeding season." Mr. 

 Elliott found them breeding upon the Pur Seal Islands and says that they are the 

 only species of the petrel kind found about this group. They reach these islands 

 very early in the season and repair to the cliffs, especially on the south and east 

 shores of St. George's Island, where, selecting some rocky shelf on the face of the 

 cliff, safe from all enemies except man, they deposit a single egg upon the bare rock 

 and proceed at once with the incubation. They are very davoted to their eggs, and 

 Mr. Elliott states that they may even be pelted to death with stones before they will 

 desert their charge. The eggs are laid by the 1st to the 5th of June, and measure 

 about 2.90x1.90. The color is soiled white; the shell is rather rough and the egg is 

 scarcely more pointed at one end than the other.
