Vou. II, Ptr. 11] GIFFORD—BIRDS OF THE GALAPAGOS ISLANDS 223 
On February 23, Mr. King found a nest with two fresh 
eggs. It was 12 feet from the ground in a bush of Zan- 
thoxylum pterota beside the wagon road on southwest 
Chatham. The nest was small and domed and built of moss 
and grass with a few small twigs interwoven. The outside 
was covered with cotton balls. The lining was of fine grass. 
One of the parents was on the nest. Both of the old birds 
were quite excited, making a clicking noise similar to that 
made by the ground and tree finches when their nests were 
disturbed. One of the birds sat on the nest site after the 
nest had been removed. 
The first young bird was taken in the interior of Charles 
on February 28. It was the only immature bird out of about 
a dozen individuals taken that day. On March 19 and 20, 
many young were met with above 300 feet on Iguana Cove 
Mountain, Albemarle. On May 25, two young in striped 
plumage were taken in the interior of Charles. Like most 
of the Galapagos land birds this species was quite tame. 
Many of the individuals taken on Chatham had swollen 
diseased feet. 
19. Certhidea cinerascens: GRAY CERTHIDEA 
Barrington, Gardner-near-Hood, and Hood islands. 
This species was quite common on Hood and the neigh- 
boring Gardner, while on Barrington it was not common. 
Unlike its congener, Darwin’s Certhidea, it was found on 
the rocks of the seashore below the high tide line, as well 
as in the brush. In fact one was seen bathing in a pool of 
sea water. ‘ 
In the bushes these birds were insect feeders, inspecting 
each branch carefully. On the rocks of the coast they prob- 
ably fed on small marine worms as did the Sooty Ground 
Finches. They were seen feeding on the seashore on Hood 
and Gardner in September and October, and in June, in com- 
pany with Sooty Ground Finches, Jamaican Yellow Warblers, 
and Hood Island Mocking birds. On Barrington they were 
seen only in the brush, where they were very hard to detect 
as they matched it almost exactly in color. On June 27, on 
Gardner-near-Hood, I saw two or three feeding on the 
ground in the open, which was unusual.
