ON THE BREEDING OF THE BLACK-THROATED BLUE WAR- 

 BLER (DENDRCEOA CJERULESCENS) 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 (Tardus nmstilinusj, 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-
