The birds have responded promptly to the changed 
conditions and this morning, as I paddled down river to 
Ball's Hill, and again at evening, on my return, I heard all 
the birds which breed along this stretch of river exept the 
Brown Thrasher, Savanna Sparrow and Bittern. I am inclined 
to think that the Thrashers have about ceased singing for 
my birds at and near Ball's Hill were also silent. I have 
not heard the Grosbeaks for several days until this morning 
when they were in full song again. The Purple Finch has 
been silent for a still longer period but one was singing 
freely this evening. The Meadow Larks have not sung much 
for a week or more but I hear their plaintive whistle a 
few times each morning and again at evening. 
A few days ago I noted the apparent absence of 
Ori©les this season along the river below the town. Up to 
that date there certainly were none along this stretch 
of river but the very next day I heard one ne ar Dakin's 
Hill and they have since steadily increased in numbers 
until to-day I must have seen or heard at least half a 
dozen. Bronzed Grackles have also become constant visitors 
to this part of the river much to the wrath and dismay of 
the Red-wings whose eggs and young doubtless form one of 
the chief attractions to the Grackles.I
