STORM PETRELS: Family Hydrobatidae [ 89 ] 



a meal of petrel eggs and young, or adults even. Jewett has one skin in 

 his collection (No. 2.860) taken July 10, 192.3, in the Willamette River 

 near Portland, certainly an odd place for a petrel. 



As in the case of other petrels, little is known of the migratory move- 

 ments of Beal's Petrels, although presumably they spend the period when 

 not breeding in wandering over the ocean. They are frequently reported 

 by travelers, but the difficulty of distinguishing the numerous species that 

 occur on the oceans of the world has prevented definite knowledge of 

 their movements. Like the less common Forked-tailed Petrel, they are 

 nocturnal, and few persons have seen them in life. With the coming of 

 dusk, they leave their nesting rocks for their feeding grounds at sea, and 

 fishermen report having heard their twittering as they traveled back and 

 forth at night.
