NO. 1727. BIRDS OF THE 1906 " I/./.' ITR088" CRl ISE CI IRK. 41 



BULWERIA BULWERJ Jardine and Selby. 

 BULWER'S PETREL. 



Bulwer's Petrel was rather common among the Linschoten Islands, 

 off the southern end of Kiusiu, and also among the Seven Islands 

 south of Yokohama. I was able to recognize this interesting species 

 at once, having previously made its acquaintance among the Azores 

 and between the Azores and Gibraltar. 



Subfamily PROCELLAIJIINJE. 



OCEANODROMA FURCATA tGmelin). 



FORK-TAILED PETREL. STURMOFKA. 



The Fork-tailed Petrel appeared as soon as we were well out to 

 sea after leaving the channel between Vancouver Island and the 

 mainland, rapidly becoming more common as we approached the 

 Aleutians, until the day before reaching Unalaska, when they were 

 very abundant. They were common in Unalga Pass, and we found 

 them on Bower's Bank and commonly about all the Aleutians, and 

 as far west as Copper Island. On Agattu they were apparently 

 breeding in holes along the sides of a deep ravine which makes in 

 from the sea at Macdonald Ba} T , most of them being met with more 

 than a quarter of a mile inland. They were frequently seen flying 

 up and down this ravine to and from the sea, and entering and 

 leaving burrows in its sides. We did not see these birds after leaving 

 Copper Island, where they were common, until we reached the 

 Kurils, where they were again rather numerous until we were south 

 of Sinmshir, after which this species was not met with again. 



OCEANODROMA LEUCORHOA ( Vieillot). 

 LEACH'S PETREL. MALINKA TSCHORNAJA STURMOFKA. 



Leach's Petrel was noticed shortly after leaving the channel be- 

 tween Vancouver [sland and the mainland, and was occasionally 

 seen all the way up to the Aleutians, although never as common as 

 0. furcata. About the islands they were sometimes seen by day, 

 but not very often; at night, however, they were attracted by the 

 lights of the ship and could be heard chirping all about, like so many 

 bats. Doubtless 0. furcata was common at night about the ship 

 also, but as all the birds which were caught on board were of the 

 present species I can make no positive statement that such was the 

 case, although 1 have examined specimens of the latter species 

 taken on shipboard at night at Kiska. After leaving Copper Island, 

 where the species was not uncommon, we did not see it again until we 

 were south of Paramushir, where it became again common until we 

 were well south of Sinmshir. The greatest number heard on any
