278 THE FUK SEALS OF THE PRIBILOF ISLANDS, 



THE BIRDS OF GUADALUPE ISLAND. 



The absence of water birds was constantly noticed. In one trip of 18 miles along 

 the western shore I saw but two gulls {Larus oceidentalis), two cormorants, and one 

 sooty albatross. Nowhere did we see any signs of the extensive breeding grounds so 

 common on the islands nearer the Mexican shore. 



But two forms of water birds were at all common. The first was the night-flying 

 petrel [Oceanodroma leucorhoa macrodactyla). This was abundant about the ship at 

 night when we were anchored near the cliffs, and specimens were repeatedly captured 

 alive. It was attracted by the fires of parties camping on the shore and was frequently 

 mistaken for a bat. 



The other water bird that was seen in large numbers was called by the sailors 

 "sea pigeon," We met them in large numbers some distance from the island, either 

 resting upon the surface or flying close to the water, but we could not get near enough 

 to identify them. It may have been the black-vented shearwater [Puffinus gaira) 

 which Mr. Walter E. Bryant saw here. The following list includes the birds identified 

 (luring the ten days from June 21 to July 1, I have followed the paper on the Orni- 

 thology of Guadalupe Island, by Walter E, Bryant (Bui, Cal. Acad. Sci., Vol, II, 269), 



1. Lams oceidentalis. Western gull. 



Two specimens, seen nearly every day on the rocks along the southern shore. 



2. Oceanodroma leucorhoa macrodactyla. Bryant's petrel. 



This little bird was very common on dark nights. It would fly around the shijj 

 uttering a peculiar cry. Occasionally one would strike the rigging and fall to the deck 

 or enter the cabin. Several specimens were secured in this way and kept alive several 

 days. 



3. Buteo borealis calurus. Western redtail 



Two specimens were seen over the southern part of the island. It was frecpiently 

 seen in the southern part. No specimens were secured, 



4. Falco sparverius. American sparrow hawk. 



5. Colaptes rufipileus. Guadalupe flicker. 



Three specimens were secured among the pines at the northern portion of the island. 



6. Micropus melanoleucus. White-throated swift. 



A swift of some kind was occasionally seen about the higher parts of the island. 

 None were secured for positive identification, and these may have been some other 

 species. 



7. CarpodacuB amplus. Guadalui)e house tinch. 



Very common about the springs on the top of the island. 



8. Junco insularis. Guadalupe Juuco. J 



Very common among the pines and cypress trees of the summit. 



9. Pipilo consobrinus. Guadalupe towhee. 



One specimen. 



10. Salpinctes guadeloupensis. Guadalupe rock wren. 



Very common everywhere, especially among the rocks along shore.
