Generally speaking, this species resembles the Whip-poor-will in 

 habits. Its notes are quite similar to those of that species, but are 

 louder, less rapidly uttered, and each call has an additional syllable. 

 Its gape is enormous, the wide-open mouth of an adult measuring 

 about two inches from corner to corner. For this reason it can swal- 

 low large objects with ease, and both Hummingbirds and Sparrows 

 have been found in Chuck-will's-widow's stomach. Perhaps they were 

 mistaken for large moths.

In walking through rather densely grown woods I have sometimes 

 been surprised by having a Whip-poor-will fly up from beneath my 

 feet and disappear in the surrounding growth. I say surprised, be- 

 cause the bird's flight is as noiseless as a moth's, and this unusual, 

 ghostly silence is almost as startling as the whir of a Grouse. 



The Whip-poor-will's day begins when the sun goes down. Then
