“He is a sort of second cousin, the same as Sooty the Chimney Swift,” explained Jenny Wren. “They look enough alike to be own cousins. Whip-poor-will has just the same kind of a big mouth and he is dressed very much like Boomer, save that there are no white patches on his wings.”
“I've noticed that,” said Peter. “That is one way I can tell them apart.”
“So you noticed that much, did you?” cried Jenny. “It does you credit, Peter. It does you credit. I wonder if you also noticed Whip-poor-will's whiskers.”
“Whiskers!” cried Peter. “Who ever heard of a bird having whiskers? You can stuff a lot down me, Jenny Wren, but there are some things I cannot swallow, and bird whiskers is one of them.”
“Nobody asked you to swallow them. Nobody wants you to swallow them,” snapped Jenny. “I don't know why a bird shouldn't have whiskers just as well as you, Peter Rabbit. Anyway, Whip-poor-will has them and that is all there is to it. It doesn't make any difference whether you believe in them or not, they are there. And I guess Whip-poor-will finds them just as useful as you find yours, and a little more so. I know this much, that if I had to catch all my food in the air I'd want whiskers and lots of them so that the insects would get tangled in them. I suppose that's what Whip-poor-will's are for.”
“I beg your pardon, Jenny Wren,” said Peter very humbly. “Of course Whip-poor-will has whiskers if you say so. By the way, do the Whip-poor-wills do any better in the matter of a nest than the Nighthawks?”
“Not a bit,” replied Jenny Wren. “Mrs. Whip-poor-will lays her eggs right on the ground, but usually in the Green Forest where it is dark and lonesome. Like Mrs. Nighthawk, she lays only two. It's the same way with another second cousin, Chuck-will's-widow.”
“Who?” cried Peter, wrinkling his brows.
“Chuck-will's-widow,” Jenny Wren fairly shouted it. “Don't you know Chuck-will's-widow?”
Peter shook his head. “I never heard of such a bird,” he confessed.
