Vou. Il, Pt. II] GIFFORD—BIRDS OF THE GALAPAGOS ISLANDS 253 
On May 16, about a quarter of a mile inland from Black 
Beach Roads, Charles, I saw a black-headed male feeding a 
young one. On the 24th another black-headed male was seen 
feeding a young one sitting on a stick about a foot from the 
ground. 
All of the other tree finches and some of the ground finches, 
also the warblers, might be considered as competitors, but the 
food supply is apparently abundant. As a rule the Black-headed 
Tree Finches fed alone. Once in the arid region of southeast 
Indefatigable I saw a Black-headed Tree Finch feeding on a 
bush in company with two Sooty Ground Finches. At another 
time on Charles they were seen feeding in tropical plum trees 
with Darwin’s Tree Finch, Small-billed Tree Finch, Sooty 
Ground Finch, and Sturdy Ground Finch. None of these 
finches are very tenacious of life. 
On Chatham, this species, like the majority of the passerine 
species with the exception of the flycatchers, was afflicted with 
diseased feet, these often having large rough swellings on 
them. Specimens from Basso Point were diseased as well as 
‘those from Wreck Bay. On Chatham, Charles, and Albemarle, 
the natural enemies of this species, aside from those indigenous 
to the islands, are cats, and to a much less degree, rats. 
34. Camarhynchus pallidus: PALLiIp TREE FINCH 
Geospiza heliobates, Snodgrass & Heller, Proc. Wash. Acad. Sci., v. 5, 
pp. 279-284; Rothschild & Hartert, Nov. Zool., v. 9, p. 400. 
Albemarle, Charles, Chatham, Duncan, Indefatigable, James, 
Jervis, Narborough, and Seymour islands. 
This tree finch occurs fairly commonly on all parts of Albe- 
marle, Indefatigable, and James, and sparingly on the other 
islands. One was taken inland from Black Beach Roads, 
Charles, on October 11, 1905. One was taken on Duncan in 
December, 1905, and several in August, 1906. Those taken in 
August were found as follows: one on northeast side of island, 
one on ridge on south side at 1000 feet elevation, and five on 
the floor of the north crater, which is about 450 feet above sea 
level and consists of reddish earth scantily clothed with vegeta- 
tion and surrounded by rocky walls 300 or 400 feet in height.
