Doubtless because we see the Nighthawk and only hear 

 the Whip-poor-will the notes of the latter have been often 

 attributed to the former, with the result that many people 

 think there is but one species. While it is true that there 

 is a general resemblance in form, in details of color and 

 markings, the two birds are quite unlike, while so far as 

 notes and habits are concerned, few members of the 

 same family differ more. The Whip-poor-will haunts the 

 shadows of the woods and rarely flies far above the ground, 

 the Nighthawk, like a Swift, courses high in the open, even 

 over city house-tops, where anyone who looks may see 

 him. The Whip-poor-will's notes have made him famous, 

 the Nighthawk calls only a nasal peent , peent, and, diving 

 earthward on set wings, produces a hollow, booming 

 sound. Both nest on the ground, but the Nighthawk 

 lays in the fields or on pebbly roofs, and its two finely 

 marked eggs (laid in May or June) are quite unlike those 

 of the Whip-poor-will.
