V "s 9 f 1 I Kennard. Habits of the Red-shouldered Hawk. 20c; 



I have since ascertained that Mr. J. A. Lowell found what 

 was probably this same pair breeding in the same locality, as 

 follows: Last of M.'iy, 1SS2, three young in a chestnut tree; 

 middle of April, 1SS3, three eggs from the same nest; May 13, 

 1SS4, two eggs in a hemlock tree (probably second brood) ; 

 April 7, 1SS7, three eggs in a white pine; thus filling out my 

 list, and accounting for this pair for every year. 



This pair seems to have shown a marked liking for a certain 

 not very large area, and they never but once strayed beyond it. 

 They never but once chose a large tree, and did not seem to 

 like evergreen trees any more than deciduous trees, and were, 

 on that account, harder to find than the West Roxbury pair. 

 They built three times in pines, twice in hemlocks, three times 

 in chestnuts, and once in an oak : only once more than forty feet 

 above the ground, and generally less, and almost always in con- 

 spicuous places. I have never known of their crossing Ham- 

 mond Street, though their territory bordered it for half a mile, 

 for on the other side of this street, and in a parallel area, is the 

 abode of the Putterham Hawks. I have but seldom seen the 

 Putterham birds cross Hammond Street, and I have never known 

 of their building on any but their own side. Their territory is 

 more compact than that of the Hammond Street pair, and contains 

 thicker woods and more evergreen trees. As they are bounded 

 on the west by the territory of the Hammond Street pair, and on 

 the south by that of the Weld Farm pair, I have noticed that 

 when not in their very particular haunts, they may be found to 

 the north and east, which is pretty well civilized. Thus it is 

 that each pair of these birds seems to hunt over its own area 

 exclusively, and by a tacit understanding, never seems to trespass 

 upon that of its neighbor. I have often been in a position to 

 hear and see both the Hammond Street and Putterham pairs 

 at once, and I have never seen them even so much as shake 

 hands over their boundary line. 



Though I had known of the Putterham Hawks for several 

 years, and had known of others finding their nests, and in 1SS4 

 had found a nest myself in a pine, that had just been robbed of 

 three eggs, it was not until 18S5, on April 19, that I got my real 

 introduction to them. This nest, containing three fresh eggs, 

 was placed about 35 feet up in a large pine, in some wet woods 

 about 150 yards from last year's nest.
