A recent study found that although there was a steady decline in the bird population of North America, there has been a considerable increase in the amount of waterfowl. Since 1979, the waterfowl population has increased by more than 56 percent. Birds like Canada geese and mallard ducks are thriving.
This is in large part due to hard-working conservationists. Ecologists have worked tirelessly for years to preserve habitats for waterfowl and protect them from human and environmental dangers. Many years and billions of dollars have been spent trying to protect these essential animals. Hopefully, these efforts will be recognized, and the same can be done to protect other avian species.
