Vot. II, Pr. 11] GIFFORD—BIRDS OF THE GALAPAGOS ISLANDS 237 
June, the majority of individuals of this species, and there 
were many of them, appeared to be immature, and but few 
black adults were seen. On south Abingdon, on September 
20, two youngsters just from the nests were seen, while Mr. 
Beck also took one. The following day three or four more 
were noted. 
Their presence on the small islet off northeast James, where 
one was observed on two visits, and on Wenman, where six 
were taken, would perhaps indicate that they move about 
somewhat from island to island. They were often seen flying. 
between Hood and the adjacent Gardner. Occasionally, when 
we were sailing about the bays in small boats, for example 
Wreck Bay, Chatham, and the harbor at Villamil, Albe- 
marle, individuals would alight on the boat, being quite fear- 
less. When anchored at Villamil, Albemarle, a short distance 
offshore, in August, several were often aboard the vessel at 
one time. 
Although they were quite tame, they were not as tame as 
the flycatchers. Birds with abnormally colored feathers 
seemed to be quite wary. A total albino was taken at Black 
Beach Roads, Charles, on October 10, by Mr. Beck. An 
adult male with a white feather in the abdominal region was 
taken on Duncan in December. Few black individuals were 
seen on Charles in May and June. On June 4 I took, at a 
spring on Charles, a bird which had several white feathers in 
its head, breast, abdomen, back, and rump, and also a pale 
primary. 
Many individuals on Chatham had diseased feet. 
A Galapagos Short-eared Owl was taken on Hood in June, 
with the remains of a Sooty Ground Finch in its stomach. It 
was captured about 10:30 A. M. 
24. Geospiza debilirostris: WEAK-BILLED GROUND FINCH 
Indefatigable, James, and Narborough islands. 
This species was common on Indefatigable and James, and 
was seen by Mr. Beck on Narborough, although not taken. 
The birds on Indefatigable are smaller than those of James, 
but, like them, were found almost entirely in the humid zone.
