have failed to detect it. Pretty clearly the individuals which are 

 seen at the marshes remain there pretty constantly the whole year, 

 for one of them is distinctively marked. 



8G. Accipilcr vclox. — Sharp-shinned Hawk. 



Tolerahly connnon the year through, hut occasionally in great 

 numbers lor a day or a week during the height of the migrations, 

 the whole length of the sand spit ; elsewhere not much increased 

 in numbers. It is seldom seen outside of thick shrubbery except in 

 its low, swift flight from one copse to another, or wheu busily en- 

 gaged eating a bird. My observations indicate that its migrations 

 pietty closely correspond with the migrations of the Olive-backed 

 Thrushes, upon which it feeds greedily. Thus, on April 29, 1907, 

 and April 27, 1908, dates when the thrushes were swarming, these 

 hawks were more numerous than I have ever seen them and were 

 fattening on thrush flesh. In a walk half the length of the sand 

 spit there v.ere many ?pots where thrushes had been caught and 

 eaten; among them only one Hermit Thrush, all the others Olive- 

 backs. During the winter this hawk not infrequently dashes into 

 town for a taste of English Sparrow. Rarely small companies are 

 seen circling and soaring high in air. I have never seen them mak- 

 ing flights northward over the lake. 



87. Acci inter cooper ii. — Cooper's Hawk. 



It is not sufficiently numerous to certainly determine its status. 

 It is occasionally seen in winter', but the indications are that it is 

 pretty regularly migratory. It is found at the nesting place about 

 the middle of April, and remains in that vicinity well into July. 

 Several have been seen at Cedar Point, but there is no good evi- 

 dence of a nesting there. It should be found nesting in the vicinity 

 of Lakeside, across the channel, and west of Marblehead. The pe- 

 culiar metallic "tick, tick, tick," which constitutes the call of this 

 ■hawk makes identification easy while it is nesting. Its fondness 

 for poultry and pigeons is pretty likely to result in its final exter- 

 mination. In the vicinity of Oberliu it builds its nest in large trees 

 in the deepest woods available, as far as practicable from the 

 ground. Crows and Jays attack it viciously. 



88. Astnr atricapilliis. — Goshawk. 



For some unaccountable reason this hawk has not come within 

 my field of vision. There is a specimen in the Oberlin collection 

 which was collected near Oberlin, so that this gives it a proper 

 place on the list. I have no question that the Goshawk is of more 

 or less regular occurrence in this region, as well as in surrounding 

 regions, and it will certainly be learned and properly noted.
