The Wood Pewee, a common summer resident, arrives in Pennsylva¬ 
nia early in May and continues with us until about September 20. This 
bird is found commonly in forests or the shady retreats of apple or¬ 
chards. During* the breeding* season, particularly, the Wood Pewee 
when perched on the dead branches of trees, watching* for his insect 
prey, utters a peculiar plaintive drawling* note—“ pe-a-wee, a-pee-wee !”— 
which once heard is rarely forg*otten. A writer has very properly said 
that these notes in the latter part of the summer are almost the only 
ones heard in the woods. The thin-bottomed, thick-walled and somewhat 
saucer-shaped nest, built usually on a thick, horizontal tree limb, is 
composed, internally, of grass stems, fine fibers of roots or other soft 
substances, and covered externally with lichens, which are held in place 
by cobwebs or “ glued to the other materials by the birds saliva.” The 
eggs, four or five in number, are yellowisli-white, with reddish-brown 
and lilac spots, generally in a ring about the larger end. They measure 
about .75 of an inch in length, and a little over .50 of an inch in width. 
I have never found Wood Pewees feeding on small fruits, but have 
always observed that they feed exclusively on insects. Audubon, how¬ 
ever, states, during the winter months, he has observed these birds in 
13 Birds.
