 plumage white. Im. — Head more or less feathered; head and neck grayish brown, blacker 

 on the nape; rest of plumage as in the adult, but more or less marked with grayish; wings and

Range. — North Carolina southward to Argentina. 



Range in North Carolina. — Occurs irregularly in summer east of the mountains. 



These great birds occur in enormous flocks about the lakes and prairies of central 

 Florida, and may also be met with numerously as far north as South Carolina, 

 where Arthur T. Wayne records them as breeding in Colleton County {Birds of 

 South Carolina, p. 26). Like the White Ibis, they migrate northward in limited 

 numbers during the summer months. One was killed early in July, 1884, at Garner, 

 near Raleigh, and a number more were reported to have been seen at the time. 

 One was secured at Chapel Hill June 12, 1901; a third specimen was taken at 

 Buffalo's Pond in Wake County, July 4, 1906; and a fourth was killed June 29, 

 1910, near Sanford. A mounted specimen, said to have been killed on the Catawba 

 River some years ago, was observed by WajTie at Morganton (see Auk, Jan., 1910).
