 are more strongly built and generally deeper, 

 and without the outside ornamentation of 

 lichens. They are saddled upon horizontal 

 branches, like those of the preceding, as a 

 rule, but are also said to have been found in 

 upright crotches like those of the Least Fly- 

 catcher. Their three or four eggs cannot be 

 distinguished from those of the eastern Wood 

 Pewee.
