July Fourth
Similar to the whip-poor-will in shape, the nighthawk, or bullbat, differs from it in song and habits,—though, oddly enough, it perches lengthwise on a limb as the whip-poor-will does. It is neither a hawk nor a bat, for it is classed close to the chimney swift, and like the swift, it is of inestimable value as an insect destroyer. It is often seen in the daytime and the large white spot on the under side of each wing helps to identify it.
