I have neighbors who frequently set out food for wildlife. I live in Champaign, so this is typically crows, other small birds, squirrels, and rabbits. Occasionally the food that's set out is sweet rolls or Oreo cookies.
Is this harmful to the native wildlife? Should I ask my neighbor, whom I'm on good terms with, to stop putting out sweet or overly-salty treats? Or are the wild animals immune to the dangers or smart enough not to eat such junk? Thank you.
