EASTERN HENSLOWS SPARROW 777 



Because of its secretiveness and of the security afforded by the 

 thick vegetation it prefers to live in, the habits and behavior of the 

 Henslow's sparrow are rather poorly known. Those of the eastern 

 race apparently differ little, if at all, from those of the more fully 

 studied western form, as described in detail in the next account.
