Buteo lineatus . 
Concord, Mass. 
Scarcity of Buteos. 
1S97. We (George Farnsworth and I) spent the forenoon sailing 
Oct. 31. on the river. Saw a Marsh Hawk and a Red-shouldered Hawk. 
The latter is actually the first Buteo that I have noted here 
this month! What a change from fifteen or twenty years ago 
when both borealis and lineatus could be seen daily almost 
anywhere about these river meadows. What has become of them 
all? They have been steadily diminishing for the past ten 
years .
