^°i"8^^^] Peabody, Nesting- of Krider's Haivk. \ \ 



Approaching stealthily a small, isolated pool a pair of Baldpates 

 is very much surprised to be so rudely disturbed and starts off with 

 exclamations of genuine disgust. 



We leave the marsh and as we near the farm a fine old Marsh 

 Hawk, with azure on his back and a ray of sunset scattered over 

 the breast, is started from a fence post. Traversing a patch of 

 high weeds we are greeted on all sides by farewells of a restless 

 throng of Tree Sparrows, assembled here to fix the day or rather 

 the night for the approaching departure. With the exception of 

 the Red-wings all birds, which we have met to-day, are only 

 transient guests, and another week or two will carry off the last 

 of them to the northward. The scene will then be changed and 

 will be very different from what we saw to-day, since other 

 forms of life will take the places of the departed ones. 



ON THE NESTING OF KRIDER'S HAWK {BUTEO

BY P. B. PEABODY. 



The following notes are based upon three years' observa- 

 tions in a region quite unfavorable to the Red-tails {Biiteo 

 borealls group), wherein, nevertheless, though I have never seen 

 a boreaUs proper, I have found krideri fairly abundant. 



The center of this region lies in Steele County, some sixty 

 miles north of the Iowa line. Northward it extends into Rice 

 County, explored, partially, for fifteen miles. To the westward 

 it extends sixty miles into Nicollet County through a well-wooded 

 region, and is practically unexplored. To the east and south of 

 the central point is no timber for miles at all suitable to Buteo- 

 nine needs. 



All this region was originally covered with heavy timber, even 

 far back from the water courses ; but the primeval trees are now 

 confined to very small and isolated patches, or to a very few
