The Chuck-Will's-Widow Is Often Mistaken For The Whip-Poor-Will

Here's a bird that is often mistaken for a whip-poor-will. This is a chuck -Will's-widow. The two birds are closely related and look very similar, if you can find one. They are very well camouflaged. And they sound very similar too.
The paintings of the whip-poor-will and the chuck-Will's-widow used in this video are by Louis Agassiz Fuertes. Birds, bird watching.
