In Ohio , a bow is legal for waterfowl .
But a crossbow is not , I think the feds banded crossbows but not sure .

I have taken 2 geese with my bow in 25 years of bow hunting and a number of ducks .
Both times I took a goose I was deer hunting , they swam down the river in range ( no deer around) and I shot one with my practice broadhead .
