that of the farmers, I made up my mind to institute a 
strict investigation of the matter. The following is the 
r esult: — 
“ When the chuck-will’ s-widow, cither male or female, 
(for each sits alternately,) has discovered that the eggs 
have been touched, it ruffles its feathers, and appears 
extremely dejected for a minute or two, after which it 
emits a low murmuring cry, scarcely audible to me, as 
I lay concealed at a distance of not more than eighteen 
Or twenty yards. At this time I have seen the other 
Parent reach the spot, Hying so low over the ground 
l bat I thought its little feet must have touched it, as it 
skimmed along, and after a few low notes and some 
gesticulations, all indicative of great distress, take an 
«gg in its large mouth, the other bird doing the same, 
When they would lly off together, skimming closely over 
the trrouud, until they disappeared among the branches 
and 'trees. But to what distance they remove their 
®ggs, 1 have never been able to ascertain ; nor have I 
ever’ had an opportunity of witnessing th® removal of 
the young. Should a person, coming upon the nest 
When the bird is sitting, refrain from . touching the 
eggs, the bird returns to them, and sits as before. 
This fact I have also ascertained by observation.”
