Once upon a time a long time ago I used to see thousands of ducks (and their hunters) in north central CA - and many many more just Northwest of Stockton. Now days very very few ducks exist in the multitude of waterways along highway 12... where they existed in the 10's of thousands 30 years ago.
A farmer up there told me he finds many of these fine game birds dead - chopped up by the wind turbines that infest that area now.
