likewise at the forking of the limb of a tree, about 20 
feet from the ground, and was composed principally of moss 
taken from the tree, two or three species being used to form 
the delicate cup. The female remained on the nest until 
frightened by the shaking of the limb. 
Close beside the wagon road connecting the wharf at 
Wreck Bay with the village of El Progreso, another nest was 
found on February 21. It was about nine feet from the 
ground in a bare bush. The female stayed on the nest, guard- 
ing zealously her one fresh egg, until I was very close. An 
egg, incubated about six days, was taken on February 23 from 
a nest in the Wreck Bay region. As usual, the nest was 
open, small, compact, shallow and like that of the Gould’s 
Vermilion Flycatcher. It was built of moss, small twigs, and 
wild cotton. It was nine feet above the ground in a tree 
close beside the wagon road. On the same day, in the same 
locality, another nest containing two fresh eggs was found. 
It was built of small twigs and moss, and placed in the fork 
of a limb of a tree 30 feet from the ground. The female 
remained on the nest while the limb was being cut off and 
hauled in, so that the nest could be reached. 
Birds in plumage intermediate between red and buff were 
rare. 
9. Nesotriccus ridgwayi: RipGway’s FLYCATCHER 
This sombre-colored little bird haunts the dense rain for- 
ests of Cocos Island, Costa Rica. It is met with singly and 
in pairs as one proceeds along the overgrown trails or works 
his way up one of the numerous streams of that island. Bating 
the Cocos Island Cuckoo, this species is the least numerous of 
the four species of land birds known from that island. Dur- 
ing our stay at Cocos in September, 1905, we usually saw 
several whenever we journeyed into the forests.
