I can guess why. Ducks and geese migrate, and I know that geese honk when they fly, because we have a lot of geese around here. Don't know about ducks. Anyway, maybe the echoes would confuse the flock, so they have developed cries that don't echo.

An echo is caused by a sound wave striking a relatively flat surface that is oriented roughly 90 degrees to the sound source, and being reflected back. By timing the delay, the distance to that surface can be determined. More than one echo can occur. Ducks flying overhead have their quacks attenuated by foliage and the sound is reflected back to the sky to be dissipated into space. The same is true for any overhead sound, not just duck quacks. That same duck held in your hands, and squeezed to make it quack, will echo if your duck call does. The proper statement should have been that quacks, or any other sound coming from overhead, usually don't echo. If there is the right kind of structure nearby that can reflect the quack to you, you will hear an echo. This kind of story going around only shows what a poor fundamental understanding of science that the average American has, and why religion and telepsychics have such a large following. People aren't interested in the real answers, only what makes them feel good. Del
