 "olive-drab to green-gray and brown, marked with several shades of chocolate

 ter to South Africa and South America. Breeds in high northern districts, and 

 winters from New York and California southward to Brazil. 



Range in Ohio. — Rare on Lake Erie in late autumn. Several records. 



LYNDS JONES in his Catalog of the Birds of Ohio, records. six in- 

 stances, with a possible seventh, of the capture of this bird within the state, 

 all since the publication of Wheaton's list of 1880. Of these six specimens, 

 four were taken at Sandusky, one near Lorain, and one "at the close of a 

 week of very stormy weather," near Lebanon. 



In habit the Parasitic Jaeger does not differ materially from the pre- 

 ceding species, but recent records would go to show that it is rather more 

 likelv to occur inland.
