Vou. Il, Pr. 11] GIFFORD—BIRDS OF THE GALAPAGOS ISLANDS 217 
mountain. On the south side of Indefatigable they were not 
seen in the damp region. On the east side of Cowley Moun- 
tain, Albemarle, they were seen as high as 2500 feet, the 
highest altitude we reached; there was practically no moist 
region, however. 
This species might be said to be more of a ground bird 
than any of the Camarhynchi. Often they were seen catching 
insects on the beaches, making dashes after them. At Acad- 
emy Bay, Indefatigable, on November 16, I saw a few feed- 
ing on the bed of a salt lagoon from which the water had 
nearly evaporated. On Jervis they were also noted on the 
lagoon beaches. In March and April they were found in the 
mangroves on the east coast of Narborough. They were 
observed commonly in similar locations on the shore of Banks 
Bay, Albemarle, in the same month. On April 15 and 16 
some were observed feeding on caterpillars. On Hood they 
were observed feeding among the rocks at low tide in com- 
pany with the Sooty Ground Finch and the Gray Certhidea. 
On Abingdon they were observed in like locations in company 
with the former species. At Villamil, Albemarle, one was 
noted in the wood pile next to a house. In the interior they 
proved to be birds of the trees and bushes. 
The first singing was heard on Duncan on December 13. 
On Chatham in January they were singing commonly in the 
Wreck Bay region. In February they were heard singing in 
the country about Sappho Cove, Chatham, and a few were 
heard in the Wreck Bay country. On February 28 birds on 
Charles were in song. In March I heard birds singing in the 
coastal region 10 miles west of Villamil, Albemarle. On 
Tagus Cove Mountain, Albemarle, they were heard as late 
as March 26 and 27. At Banks Bay, Albemarle, April 10, 
one or two were singing in the mangroves. April 25, ten 
miles west of Villamil, Albemarle, they were singing, while 
in latter May none were in song on Charles. 
The condition of the reproductive organs was noted as 
follows: 
January 25; Wreck Bay, Chatham; sexual organs large. 
February 23; Wreck Bay, Chatham; large sexual organs. 
May 13; ten miles west of Villamil, Albemarle; large sexual organs. 
May 14, 15; Black Beach Roads, Charles; sexual organs reduced in size.
