Windy storms definitely have an effect on dove populations. Doves will try to build a nest on a flag pole. They have multiple broods each year so one storm won't ruin things but multiple storms could have an effect.

I can't convince myself that more food, more corn piles, more sunflowers, etc. would be harmful to the dove population. It may spread them out short term but overall, it would help survival for next year's breeding birds.
