limit of the Turkey Vulture along the Atlantic seacoast. The 

 factor of timber land interposing has been used, because the 

 birds can be observed at such a long distance, that woods close 

 at hand would cut ojff open country beyond, and again this 

 species may be found in woods, feeding when opportunity 

 offers, and frequently roosting there in the day time, and then 

 they are not likely to be seen in passing. 



The separate figures represent separate observations (birds 

 close together or in the same immediate neighborhood) and are 

 given to indicate better the distribution of this bird throughout 

 the region. 



It has been assumed that the observer was able to see a belt 

 one mile wide, an arbitrary assumption dependent on various 

 conditions, including height of the bird above the earth, but 

 numerous observations suggest this distance as being within 

 bounds.
