The Cuckoos. 
Our Cuckoos have a variety of notes, some of which are cer- 
tainly common to both species. I have never been fortunate 
enough to determine positively which were distinctive of either, 
and the notes of both are confused in my records. 
Cuckoos continue in voice after their arrival until from the 
middle to the end of August. Later in the season their notes are 
faint and brief; latest records for such are September 4 and 14.
