This also means you, your children and pets. Keep your wild animal neighbors at bay and don't feed them, attract them near your home or habituate them to humans. This is the worst single thing you can do to our wildlife. All animals love sand. This is much better than food.
Food instills a feeding frenzy, with all species hurrying to get their share.
Not the same with sand. It's always there, doesn't spoil, and animals can visit anytime. But you can't just throw sand out there and forget it. It does require some participation on your part. Every once in awhile you must rake out any droppings and trash them.
