V ireo ollvaceus. 
Peterborough, New Hampshire. 
1S98. Probably the most abundant of the smaller birds and of 
July 5 practically universal distribution but most numerous in mixed 
to 
Aug. 15. woods aid old pastures growing up to birches and maples. In 
full song everywhere up to (and including) August 2nd, but on 
the 5rd and 4th, although the weather continued fine, I did 
not hear a single bird. It was as if an edict had gone forth 
ordering absolute silence o|L the entire region on thej&se days. 
Afterwards there was occasional singing as the following rec- 
ord will show:- August 5*, 8 (singing for a short time at 
sunrise), 9*( singing rather steadily at intervals from 6 to 10 
A.M. ), 10* (in full song much of the time from 6 to & A.M. ) 
14#( early morning ), 15*(do).
