thorn bush. It contained four eggs which had been broken 
when fresh; perhaps the work of rats or mice. A small spider 
was found in one. 
Like the nests of all of the Galapagos finches, the nest of 
this species is domed and has a side entrance. An exception 
to this rule was once seen in a nest built in a curled cactus 
leaf, which had entrances on two opposite sides. The nests 
were usually built of coarse grass and cotton balls lined with 
fine grass and cotton. Sometimes they were lined with the 
bushy tops of grass. I saw an old nest utilized, the owners 
making a new entrance of fresher dried grass for it. Often 
the nests were composed largely of orchilla moss or lichens, 
instead of grass, when built in a region where the grass was 
very scarce. Sometimes both were used. Leaf fibre was also 
used to some extent, often along with orchilla moss. Creep- 
ers and small vines were limited in their use to the regions 
where they occurred. Once in a while feathers were used in 
the lining of a nest, although very rarely. In several cases 
green grass was used along with the dry material. The hair 
of cows, pigs, and donkeys was used to a small extent in 
lining the nests. Mr. Beck found a nest with a large entrance 
and of peculiar construction, being made with the heads of a 
small weed, all the stalks facing the same way. Once or 
twice long narrow nests were found. 
When a nest was disturbed the owners usually stayed close 
by, making a clicking noise. 
Apparently the first young bird was noted on Chatham, 
February 23. It was a well-fledged one, which flew from a 
nest containing five eggs nearly ready to hatch. On March 
13, about 10 miles west of Villamil, Albemarle, I saw one 
following its parent about and being fed. Two days later, 
near Cape Rose, Albemarle, I saw a young bird fresh from 
the nest. At Iguana Cove, Albemarle, March 18, one or two 
young birds were noted. At about 1500 feet on the west 
side of Tagus Cove Mountain, Albemarle, on April 2, I saw 
several in the brush during the afternoon. On April 4, on 
the same mountain, a nest of five young was found; they had 
their eyes open, but were unfledged. On April 12, 13, and 
14 young birds were found quite commonly on Banks Bay 
Mountain, Albemarle. On Charles, in latter May and early
