114 GEOLOGICAL SURVEY OF ALABAMA 
Though the foregoing is the only note on the yellow- 
throated warbler published by the Doctor, he afterwards 
recorded rather extended observations on the nesting of 
the species. These original notes follow: 
“April 2, 1898. No. 1. Asbury McShan found a yel- 
low-throated warbler building in a sweet gum tree not 
far from the Greensboro station, and just over the path, 
in a pendant bunch of gray moss about forty-five feet 
from the ground. She could be plainly seen with a field 
glass through the moss whenever she brought material 
to the nest. 
“On the third and fourth she was occupied morning 
and evening at her work. At six o’clock she was work- 
ing on the third; and later still she could be seen ’till 
almost night at her labor. 
“The male was heard singing some distance from the 
scene of his mate’s constant occupation, for many hours; 
and he seemed quite indifferent to what she was doing, 
though perhaps she listened to his song attentively, and 
found relief in the sweet music of her charmer. 
“She flew generally to the limb from which the moss 
hung and ran down till she reached the bunch when she 
fluttered like a butterfly before the opening on the side 
of the moss and then vanished in the waving epiphyte, 
soon to emerge and to dart so swiftly forth that the eye 
could scarcely follow her as she wound her aerial journey 
now through the tree tops, and now suddenly descending 
and skimming along the ground to seek rootlets or straw 
or vegetable down for her cosy nest. I saw her once tear 
the lining from an old nest of last year—a brown thrash- 
er’s I believe. 
“What instinct compels these birds thus to conceal 
their nests in this pendent moss? Is it the inherited 
memory of hundreds of ancestors that have built in vain 
upon the bare branches till they have sought concealment 
and safety in their rocking cradles upon the tallest trees? 
Has the cunning serpent or the jay robbed them of their 
treasures till the instinct of concealment is common to 
these denizens of the lofty forest trees? . 
“April 4, 1893. No. 2. Asbury found a nest of D. 
dominica this afternoon. It is in a bunch of Tillandsia
