Vou. II, Pr. 11] GIFFORD—BIRDS OF THE GALAPAGOS ISLANDS 245 
while feeding. It could not be heard at any distance, being a 
tweet and then a prolonged fwiir. 
Birds with large sexual organs were noted on November 3 
at Villamil, Albemarle; on February 8 at Basso Point, Chat- 
ham; and on March 13, ten miles west of Villamil, Albe- 
marle. Specimens taken on Charles on May 14 and 15 had 
sexual.organs much reduced in size. 
Nests and eggs were found as follows: 
Mr. Beck took a nest, containing four eggs incubated four 
days, on February 23, in the Wreck Bay region, Chatham. The 
female was flushed from the nest which was of the domed form 
common to all Galapagos finches. It had a large entrance and 
was composed of dry grass, weed stems, and orchilla moss. 
The depression in which the eggs were laid was only slight. 
Mr. Beck took a second nest of this species on the same day 
and in the same locality. It contained four eggs incubated three 
days. The nest was 18 feet from the ground in a tree, and 
was composed of small twigs, grass, and weed stems, and a 
large amount of orchilla moss. 
Above 1900 feet elevation on Banks Bay Mountain, Albe- 
marle, April 14, this species was the only finch seen. At 1900 
feet I took a nest from the crotch of a croton bush. It was 
about 10 feet from the ground and contained three fresh eggs. 
It was large and made of grass, lined with fine grass. The 
parents stayed very close, making a clicking noise. 
A young bird fresh from the nest was taken on March 15, on 
the edge of a mangrose swamp near Cape Rose, Albemarle. 
Many of the birds seen on Banks Bay Mountain on April 14 
were young birds. 
This species did not associate regularly with other species. 
The cases observed appeared to be accidental. As it seemed to 
live on vegetable matter, it did not appear as though it had 
much competition with other species, the food supply being un- 
limited. 
These tree finches were quite tame, although not as tame as 
were the flycatchers. In one case one was very inquisitive, fly- 
ing to within a couple of feet of my face, and acting somewhat 
like a Galapagos Flycatcher. At another time one alighted in 
a tree above me, then flew down within two feet of me to make 
a critical examination, singing all the time.
