Red-shouldered Hawk. 



To man}' readers of the Oologist a 

 paper on the nesting habits of so com- 

 mon a bird will be worth reading, if at 

 all, simply to compare with their own 

 notes on the same subject. Other col- 



lectors and bird stud«rits, who are with- 

 out the habitat of the Red shouldered 

 Hawk, may glean therefrom some bit of 

 knowledge of its life habits, and this ad- 

 vances some apology for its appear- 

 ance. 



The locality which this hawk chooses 

 for its nesting site is usually an oak or 

 chestnut grove, when upland, and a 

 maple grove when in the swamp; never, 

 in any case, fai from running stream or 

 swamp, and commonly near to farm 

 buildings. The nest is composed of 

 goodly size sticks, so arranged as to 

 leave a hollow in the center, into which 

 is placed a large quantity of the inner 

 bark of the chestnut tree— a nest which 

 was built this year, and which I have 

 in my den, contains enough of this inner 

 bark to fill a peck measure. Around 

 the outer edge of the nest, on the top, 

 is almost invariably placed a few fresh 

 branches of some species of the ever- 

 green tree. The nest contains no other 

 lining than the inner bark. After in- 

 cubation begins numerous feathers 

 from the bodies of the parent birds, ac- 

 cumulate in and about the nest, often- 

 times giving it the appearance of a 

 feathered lining; and as incubation ad- 

 vances the feathers cling to the outer 

 ends of the nest-sticks, some nests be- 

 coming completely feather- bedecked by 

 the time the young put in an appear- 

 ance; while in all cases at least a few of 

 the tell-tale feathers are there to pro- 

 claim to the trained eye the stage of nid- 

 itication. The nest measures outward- 

 ly two feet across when the situation 

 permits of the nest being built round, 

 though from its location in the crotch 

 of the tree, the nest is not always so 

 built (not measuring extreme single 

 nest-sticks which would frequently add 

 another foot), and varies from eight to
