tie fighting between the Red-tails and the Rough-legs. All of the 

 birds were circling upward, but the Red-tails and Red-shoulders 

 did not ascend far. The other occasion was April 29, 1907, at Rye 

 Beach, where the numbers were too gi'eat to be counted. These 

 Broad-wings wei'e near the ground when first seen, but rapidly as- 

 cended in spirals, all the while moving nearly parallel to the lake 

 shore in an easterly direction. When they disappeared from view 

 high up they were still drifting eastward over the land. In this com- 

 pany there were Sparrow, Marsh, and Rough-legged Hawks, four 

 of eadi, which did not accompany the Broad-wings far. When 

 these birds were first seen they were about two miles west of the 

 east end of" the marshes, and therefore within plain view of Kel- 

 ley's Island. It seems likely that they had arrived over the San- 

 dusky river route, and therefore reached the lake shore, or the 

 marshes, near Sandusky. It is difficult to account for their east- 

 erly course if, as seems almost certain, fhey were bent on reaching 

 the Canada side. At their elevation of several hundred feet they 

 must have been able to see not only Kelley's, but also Pelee Island, 

 and probably also Point Pelee. If they were afraid to cross such an 

 expanse of water they ought to have had sense enough to cross by 

 the island route, and if they were not afraid to cross anywhere 

 what was the sense in their cringing along the shoi'e? If this were 

 an isolated instance one might argue unfamiliarity with the route, 

 but the same direction has been taken on each of six such migra- 

 tions. It may be, therefore, that this species is following an heredi- 

 tary instinct. 



The few nests found have invariably been in the smaller stream 

 gorges situated well up in trees growing from the bottom of the 

 gorge. The immediate vicinity of Cedar Point is therefore not suit- 

 able for the nesting of the Broad-wing. 



92. Archibuteo lagopus sancti-johannis. — Rough-legged Hawk. 



A winter visitor in small numbers, tarrying, sometimes, into May. 

 Contrary to my experiences with this hawk in other localities, it is 

 not found here about the marshes in winter, but hunting over the 

 fields and meadows. It is hardly more tlian occasional, and some 

 winters is not noted at all. ]\Iy dates of occurrence are too few and 

 too scattering to give any indication of the times of migration. 

 This is one of the mouse hawks feeding largely upon such small 

 mammals. 



93. Aquila chrysaetos. — Golden Eagle. 



One was recorded about the middle of the sand spit, March 2. 

 1908, which is the only one recorded for the immediate vicinity of 

 Cedar Point. There are several other winter records for the east-
