Connecticut 
Warbler 
on 
Ball’s H ill 
Its call or 
alarm note 
About 7 A. M, before the wind rose, I was strolling 
through the opening behind Ball's Hill when I heard a sharp, 
metallic, finch-like note, not unlike that used occasionally 
by the Black and Yellow Y/arbler (Dendroeca maculosa ) 
but much louder and stronger. This I recognized at once 
as the characteristic alarm note of the Connecticut Warbler, 
Steadily increasing in emphasis and frequency of utterance, 
it was repeated scores of times at short int ervals. Presently 
I sa,w the bird flitting about in a thicket of young black 
spruces on the northern slope of the hill only a little 
below the crest. When I got within 20 yards or so, it flew 
to another cluster of spruces. For several minutes more it 
continued chirping and acted as if were much excited, 
although I could see nothing to alarm it. Evidently I was 
not the disturbing cause, for I was 100 yards off at the 
back of the hill, when I first heard it. At length it 
quieted down and began rambling about over the ground, walkirg 
with a smooth, gliding motion much like that of an Oven- 
bird. I now got within ten yards and had an excellent view 
of it. It;^ was either a female or a juvenile make, having 
a plain, buffy throat. Its call note was invariably the 
same and closely similar to that of the Mourning Warbler. 
I know no other Warbler which makes such a sound except, as 
I have said, Dendroeca maculosa.
