“ THE BLACKBURNIAN WARBLER. 927 
This nest was built in a low barberry-bush in Waltham: it 
was constructed of fine grasses and the down from ferns. 
These materials were carefully woven together into a neat 
fabric, which was lined with cottony substances and a few 
horsehairs. The eggs were three in number: these were 
of a creamy-white color, covered sparsely with spots and 
‘blotches of different shades of reddish-brown, thickest at 
the large end of the egg. Dimensions of the eggs: .68 by 
.00 inch, .67 by .50 inch, .66 by .49 inch. Audubon 
describes a nest and eggs sent him from Nova Scotia as 
follows : — 
“Tt resembles that of the Sylvia estiva of Latham, being firm, 
compact, the outer parts formed of silky fibres from different plants, 
attached to the twigs near it by means of glutinous matter, mixed 
with the inner bark of some tree unknown to me. Within this is 
a deep and warm bed of thistle-down, and the inner layer consists 
of feathers and the fine hair of small quadrupeds. 
“ The eggs are rather large, of a light rosy tint, the shell thin 
and transparent : they are sparingly dotted with reddish-brown near 
the larger end, but in a circular manner, so that the extremity is 
unspotted.” 
From the last of September until the middle of October. 
they become very plentiful again, and may be seen in large 
detached flocks in all the fields, orchards, and woods of the 
country: they are very abundant in stubble-fields; and I 
have seen as many as fifty in a flock start at the report of 
my gun, when I have been quail-shooting.
