Why are those ducklings in the storm drain?…and so on.

Today, the fate of wildlife diversity, both locally and globally, is largely determined by the actions of sprawling masses of humans. If the conservation/preservation mindset of the public at large fails to broaden beyond lawn care, outdoor recreation, pet-keeping, and the hysteria of cute animal rescue, then at-risk species will have no real chance of long-term survival.

What does all that mean? It means you can stop feeding ducks now. It’s a good start.

Hand-fed waterfowl like these Mallards (polygamous form) quickly domesticate and lose their instinct to migrate. They soon become accustomed to human activity and begin wandering fearlessly into traffic where they are hazards not only to themselves, but to people too. Their incessant foraging within a small range pollutes water, degrades fisheries, and obliterates aquatic food chains, often extirpating entire populations of native plants and animals from local streams and wetlands. The irony of it all: duck feeding damages vital resting and breeding habitats needed by migrating waterfowl, the truly wild ducks and geese. So if you really love ducks, don't feed them. See how easy that is?
