Vou. II, Pr. 11] GIFFORD—BIRDS OF THE GALAPAGOS ISLANDS 247 
Three black-headed males were taken in the humid zone of 
James on December 22 and one on Jervis on the preceding day. 
With the Jervis male was also taken a female. Birds taken 
on James in early January showed enlargement of the sexual 
organs. Mr. Beck took a large-billed, black-headed male at 
Academy Bay, Indefatigable, on July 17.

Abingdon and Bindloe islands. 
This species was found equally as common on Bindloe as on 
Abingdon. We visited both of these islands in September. 
Nineteen were taken on northwest Bindloe on the seven- 
teenth. The following morning Mr. Beck spent an hour ashore 
and secured six. They were all taken in the arid region, as 
there is really no humid belt on this island. 
On the south side of Abingdon they were found in both the 
arid and humid regions. One was taken just below the dense 
growth of ferns capping the summit of the island, which was 
enveloped in fog during the five days of our stay. 
Like the other tree finches, this species feeds in the trees and 
bushes, being seen in the dry brush in the arid region. 
On September 21 Mr. Hunter took a female with an egg 
almost ready to be laid. On the same day I took about 10 
young birds. Of the 25 specimens taken on Bindloe, six 
were black-headed. I noticed but one black-headed one on 
Abingdon. 
This species proved as tame as the majority of finches of the 
islands. 
It fed singly and not in flocks as did the majority of the 
ground finches.

Albemarle, Duncan, James, and Narborough islands. 
The Allied Tree Finch was not found commonly on any of 
the above islands except at Iguana Cove, Albemarle, where 
27 were taken in the humid region on March 19 and 20. We
