337. Buteo borealis (Gmel.). REn-TAiLED Hawk. 

 All abundant niii^rant both in the sprint; and in the autumn, 

 sometimes passing through the Connecticut \-alle\' in small 

 flocks; also a tolerabl\- common summer and rare winter 

 resident. 



339. Buteo lineatus (Gmel.). Red-shouldered 

 Hawk. \'ery common summer but rare winter resident; I 

 think this hawk breeds here in greater numbers than all other 

 kinds put together. 



343. Buteo latissimus (Wils. ). Broad-winged 

 Hawk. Breeds regularly and commonl\- in the mountains 

 west of Westfield; rare in the ri\er towns during the s])ring 

 and autumn. 



347. a Archibuteo lagopus sancti-johannis (Gmel.). 



American Roi'Gh-le(h;ed Hawk. A common winter visitor, 

 btit not so numerou;^ as ten years ago. While here it feeds 

 entirely on mice and other rodents; if the ground is covered 

 with snow to a great depth, the difficulty of obtaining food 

 causes it to move further south, but it always returns soon 

 after the snow melts and a substantial portion of the ground is 

 uncovered. 



349. Aquila chrysaetos (I/inn. ). Golden Eagle. 

 There are no late records of the appearance of the Golden Eagle 

 in this vicinity; one was taken in Monson, in November, 1864, 

 and two were captured in Westfield, two years later. (See 

 Allen's Rarer Birds of Massachusetts.) 



352. Haliseetus leucocephalus (lyinn.). Bald 

 Eagle. Rather uncommon transient \-i-itor in the spring, 

 summer and autumn, and rare in the winter. Dr. J. A. Allen 

 reported it as sometimes breeding. Occasionally it is quite 

 numerous near the river in late summer, feeding on the dead 

 fish that are often to be found in large numbers at that .season. 

 On Mt. Tom, once, I saw a Duck Hawk make a .savage attack 

 on a Bald Eagle and dri\-e it from the mountain.
