This species, along with other passerine birds on Chatham, 
had diseased feet, the disease manifesting itself by large 
rounded swellings on toes, tarsi, and at the junction of the tarsi 
and the tibiz. Birds in the vicinity of Basso Point, as well as 
those at Wreck Bay, were affected. 
Black-headed males were not uncommon, except on Chat- 
ham, where only one was taken, and that in January. This case 
is nearly parallel to that of the Black-headed Tree Finch on that 
island. 
29. Camarhynchus psittaculus: Parrot TREE FINCH 
Barrington, Charles, Chatham, Duncan, Indefatigable, 
James, and Jervis islands. 
The Parrot Tree Finch was apparently one of the rarest of 
the finches of the Galapagos Islands, being found very spar- 
ingly on the above islands, chiefly on Indefatigable and James. 
They were found in the arid regions of all the islands men- 
tioned except Chatham, and also in the humid regions of 
Charles, Indefatigable, and James. One was taken in the 
north crater of Duncan at an elevation of 450 feet. On the 
same day, August 15, 1906, three others were taken on a ridge 
at about 1000 feet altitude on the south side of the island. One 
was seen in the arid region of northeast James, as well as in 
that back of James Bay. 
Like the other finches of the genus they lived up to their 
name of tree finch, being observed with one exception to feed in 
the trees and bushes, often hanging head downwards in the 
search of some dainty morsel. Never more than one or two 
were seen at a time, nor were they ever seen in company with 
cther species. One was seen at about 375 feet elevation on 
south Indefatigable, feeding on heliotrope blossoms, when sud- 
denly a mockingbird swooped at it and drove it away. The 
exception to the rule of feeding in trees and bushes was noted 
in the upper part of the arid region inland from Academy Bay, 
Indefatigable. There a bird was seen beside a fallen, rotten 
log, scratching the dirt away very vigorously. 
Four or five were seen in July, about the freshwater hole at 
the beach at Academy Bay. Although rare, these birds were 
always very tame like the other finches.
