Probably you don't know that there are 2 kinds of feather hunters, one shoot birds in fly only and second only on the ground or on the water. Second hunters are proud of their abilities to land bird on the ground and its not easy sometimes. Personally I used both tactics, but prefer to shoot flying as well.
Re. American videos - I saw a lot of times on professional call makers videos, like some professionals shoot ducks right on the water.
And last, there was old Russian tradition to shoot the whole flock right on the ground or water from big bore guns.
