Ball's Hill, Concord, Ivlass. 

 1897. A year or tvv-o ago I noticed v/hat seemed to be a small 



April. spring Robin roost in some dense yoimg pines on the N.E. side 

 of Ball's Hill. This season I have seen the toirds there on 

 only one occasion, viz. April 26th when between s\mset and 

 darl; a dozen or more came in from different directions biit 

 chiefly from the S. and 3.\V, I think they were all males for 

 nearly if not quite every one sang for a few minutes just be- 

 fore darlv raalving a fine chorus. A strong and exceedingly 

 chilly S.W. wind was blowing this evening and they doubtless 

 sought shelter from it among these pines under the lea of the 

 • high ridge. Robins have been scarcer than usual at Concord 

 this spring.
