The hulk of the migrating Crows passed south this year 
between the 14th and 27th of October during which period I 
saw some very large flocks at Ball's Hill, their favorite re- 
sort while pausing to rest and feed before pushing on their 
journey. After the 27th this region was apparently frequented 
by only the local birds which will pass the winter there.
