AVERY BIRD COLLECTION Da 
have elapsed since it was finished. Asa rule not less than 
- eighteen days should be allowed from the time the nest 
is done till it is taken. 
“April 18, 1898. No. 4. The nest in the pine tree 
proved to have a set of five eggs slightly incubated. It 
was built on a pine limb, and so concealed as to be found 
only by seeing the old bird take the nest. This was 
twenty-five feet from the ground and seven and a half 
feet from the axis of the tree. 
“External width of nest 2.90 inches; internal width 
1.65 inches; external depth 3.00 inches; internal depth 
1.70 inches. Material: strips of bark and straw on the 
outside, attached to the limb of the pine by a substance 
resembling spider web and giving the nest a grayish ap- 
pearance externally; inside of nest lined with hairs, ap- 
parently of the cow, and with feathers. 
“April 20, 1898. No. 5. A yellow-throated warbler 
was discovered building her nest this afternoon in a sweet 
gum. The nest is completely concealed in a bunch of 
moss and is at least fifty-five or sixty feet from the 
ground, and on the end of a limb. The male and female 
were observed feeding together; they visited several 
bunches of moss; at last they both flew high up to a moss 
covered branch and disappeared in the moss; the male 
then left his companion, and she was observed many times 
to dart to the earth and return to the bunch of moss. It 
was evident after she had many times flown to and from 
the moss that she was building. 
“April 24, 1898. No. 3. No. three’s nest (D. domin- 
ica) was taken this afternoon. It contained four slightly 
incubated eggs. Nest was on the horizontal limb of a 
sweet gum, 26 ft. from the ground and 9 ft. from the 
body of the tree. 
“The parent remained on the nest till she was shaken 
from it by the jarring of a pole on the limb. This nest 
was found on the evening of the 10th; it was taken on the 
24th, just fourteen days from the time it was first dis- 
covered. The bird was last seen building on the 12th; 
she was then lining the nest, as I saw her carrying a 
large feather in her bill.
