As I was returning from the Barrett farm shortly after 
noon 1 heard Crows cawing and looking up saw a flock of fully 
five hundred nearly over Ball's Hill and at fully the eleva- 
tion at which Wild Geese ordinarily fly when on r/iigrat ion. The 
Crows were coining from the N.E. and were evidently looking 
for a place to alight or rather, as I felt assured by their 
behavior, were heading towards a place where at least some of 
them had often halted to rest and feed in former migrations. 
After circling a few times they descended to the fields beyond 
Benson's and behind Holden's Hill, where I heard them cawing 
every now and then during the remainder of the afternoon. This 
is the first migratory flock that I have seen here this au- 
tumn. 
The Crows that arrived yesterday from the north were here 
through the forenoon - at least two hundred or more of them 
were - flying about in detachments cawing noisily. 
, Mass. March birds in the Garden. 
Seen every few days, flying overhead or perched in the 
lindens, usually in pairs, never more than three or four to- 
gether, very noisy after the middle of the month. I am satis- 
fied that these birds are the same individuals which visited 
our place in January , arpd February and that they are also the 
birds which creed in this neighborhood.
