Birds of South-eastern Indiana. 

 By RuFus Haymond, M. D. 



Genus HALLETUS, Sav. 



HALiiETua LEUCOCEPHALUS, Linn. The Bald Eagle. 



A few of these noble birds still linger in this section of the country. I have 

 observed one or two of them each winter for the last twenty-five years. They 

 are rarely seen at any other season of the year. 



Genus PANDION, Sav. 



Pamdion Hali^tus, Linn. Osprey, or Fish Hawk. 



Common during spring and autumn, but more abundant during the latter 

 season. 



Pandion Washinqtonii. Bird of Washington. 



Falco Washingtonii, Aud. 



This bird has been observed on white Water River by some of our older citi- 

 zens, every fall and winter for more than forty years. I have myself observed 

 one or more of them almost every winter for more than twenty years. Their 

 habits being almost identical with those of the Osprey, I have placed them, 

 without any other authority, in the same genus. 



Genus FALCO, Linn. 



Palco palumbarius. Goshawk. 



These hawks are quite numerous in all the wooded districts of the western 

 country.
