ON THE BREEDING OF THE BLACK-THROATED BLUE WAR- 
BLER (DENDR(EQA CMRULESCENS) IN CONNECTICUT. 
BY C. M. JONES, 
As but little is known concerning the nesting of this warbler, 
a description of two instances which have come under my ob- 
servation may not be without interest. But perhaps the most 
interesting fact connected with the discovery of these nests is 
the occurrence of this species, during the breeding season, so 
far south of its usual summer habitat. Eastford, where they 
were found, is in the north-east corner of Connecticut, being 
eight miles south of the Massachusetts line, and sixteen miles 
west of the Rhode Island line. 
My first discovery of the nest of this bird was on the 8th of 
June, 1874. While taking a stroll in search of specimens for 
my cabinet, my attention was arrested by a bird of which I 
could not determine the species. I tried to get a shot, but 
it was in the tops of the trees, and kept flitting about so rap- 
idly that I could only keep it in view sufficiently to follow, 
which I did for, perhaps, seventy-five yards, and then lost sight 
of it entirely. But just then I discovered a nest of the Wood 
Thrush (Turdus mustilinu^J, proceeded to appropriate the 
eggs, and had scarcely finished packing them, when I again 
discovered the bird, of which I had been in pursuit, in a 
bush not more than a dozen yards off, and from her restless 
manner I was convinced that it had a nest very near. I ac- 
cordingly retired a short distance, and sat down to await further 
developments. Presently it flew near the Thrush’s nest, and 
after waiting a few moments, dropped into a low bush and dis- 
appeared. Allowing it sufficient time to get settled, I care- 
fully approached the spot, and, looking under the low bush- 
es, discovered it sitting on a nest, not more than two feet 
from where I stood while taking the Thrush’s eggs. The bird 
let me approach within a yard before starting, and then, hop-
