Vol. II, Pt. I] GIFFORD— BIRDS OF THE GALAPAGOS ISLANDS 103 



and feet red. The remaining bird, an adult male, had a bright 

 red gular sac. 



The farthest south we .saw the Man-o'-war Bird was lati- 

 tude 3° 41' South on June 12, 1906. East of the archipelago 

 we met with it occasionally on the ocean, but it was nowhere 

 seen in any numbers except at Manta Bay, Ecuador. 



On the voyage out from San Francisco we saw the first 

 Man-o'-war Bird at the Tropic of Cancer on July 22, At San 

 Benedicto, Revilla Gigedo Islands, they were nesting abun- 

 dantly on July 26, the nests being situated on the low land as 

 well as on a high mesa. The nests were built on the top o£ 

 clumps of grass, and in most cases contained a single white 

 fresh egg. Six nests out of about two hundred contained 

 two eggs each. 



On July 27 and 28 we saw a number of Man-o'-war Birds 

 about the coast of the neighboring Socorro Island. On the 

 voyage from Socorro to Clipperton Island, Mexico, they were 

 seen occasionally. At Clipperton, August 10, we saw none 

 on the island, but there were two or three hundred sailing 

 over it during the forenoon. About noon they all headed 

 out to sea in an easterly direction. 



Between Clipperton and Cocos Island, Costa Rica, a few 

 were seen. At Cocos, during the first half of September, they 

 were very common over the water and in the high trees in the 

 forest. Many males in fine glistening black plumage were 

 observed flying about with their bright red pouches distended ; 

 so, evidently, September was the opening of the breeding- 

 season, and undoubtedly the nests were placed in the tops of 

 the tall trees, where so many of the birds could be seen and 

 heard. At Cocos they persecuted the small Clipperton Nod- 

 dies as well as the boobies. 



On the voyage home from Culpepper Island, we saw several 

 on September 26th in latitude 3° 29' North, longitude 93° 6' 

 West; on the 27th in latitude 5° 34' North, longitude 95° 27'. 

 West. Then came a hiatus until October 7th, when one was 

 seen in latitude 14° 38' North, longitude 109° 12' West. After 

 that they were seen every day or so until October 24th, lati- 

 tude 19° North, longitude 116° 41' West. They frequently 

 made unsuccessful attempts to alight on the topmast of the 

 schooner.
