105. FORK-TAILEB PETREL. Ooeanodroma furoata (Gmel.) Geog. Dist.— 

 Pacific Ocean, on the American coast soirth to, Oregon. 



On all of the less populated islands of the Aleutian group as far east as TJnalaska 

 this species is found breeding in the month of June. The nests are made in burrows 

 or holes about a foot deep in steep banks; the termination of the cavity being thinly 

 lined with fine roots and dry grass. This species, like Leach's Petrel,, when caught 

 has the habit of ejecting a reddish oily fluid which ha-s a strong, disagreeable smell; 

 the nest, eggs, and even the old dry skins of the birds arc forever infected with it.
