NIGHTHAWK
Then he does not act like the whip-poor-will. He is a high flyer, sailing about over our heads in the afternoon or evening. He is not silent on the wing. Now and then he gives a strange sharp cry like "peent." He is busy catching flies and mosquitoes as he goes. Sometimes you will see him dive head first toward the earth as if he would dash himself against it. At the same time he makes a loud sound, like blowing into the bunghole of an empty barrel. But before he touches, he turns and skims along just above the ground.
The mother nighthawk, like the whip-poor-will, makes no nest. She chooses a sunny spot in a pasture or on a hillside to put her eggs. Sometimes in the cities, where flies and other things to eat are so plentiful, she takes a flat house-roof for her nursery. Many pairs of down-covered baby night hawks are brought up over our heads, and we do not know it.
The family name of Goatsuckers was given to the birds from the foolish notion that they took milk from the goats. By watching them, it has been found that when they are so busy around the goats or cattle, they are really catching the insects which torment them. So they are doing a kindness to the beasts, instead of an injury.
