habits are not materially different. Dr. Coues says 
of the latter, “It is a bird of open country, the Fly- 
catcher of the plains. . . . It has the same vibrating 
motion of the tail so characteristic of the Eastern 
pewee.” 
In New England and “higher mountain districts 
of the United States” is found the Olive-sided Fly- 
catcher, which does not with any show of regularity 
visit the lowland tracts of the Middle States, although 
they have been found in the neighborhood of Phila- 
delphia. As a Colorado bird, it is described as keep- 
ing to ‘‘the tops of the trees, and is an active flycatcher ; 
its voice is loud and distinct, and its nest is placed in 
the top of a pine and zealously guarded from all in- 
trusion with as much fierceness and energy as the 
kingbird’s.” 
The Wood Pewee is almost as common as the 
pheebe bird, but it has not yet become so familiar as 
to nest otherwheres than in trees, and among them it 
passes the whole summer away. It comes to the 
Middle States in April and disappears some time 
before the common pewees have departed. While 
not a shy bird as I have seen it, it prefers shade to 
sunshine and tall trees to scrubby ones. It loves an 
orchard, but it must be one of the old-fashioned kind, 
with enough of general neglect about it to attract 
insects of all kinds. Then, too, the trees must be 
large and have in their branches a good range of 
hunting ground. I have often been amused at the 
diving for insects practised by these birds. Perched 
on a dead twig of some tall tree projecting into open 
space, the wood pewee will look down for insects
