Kids love growing their own plants.
Where there are plants, & sources of water, there are wildlife creatures living and feeding among them.
Birds are great seed spreaders and pollinators. They are also helpful in keeping the insect population under control.
Birds enchant us with their lovely songs and kids enjoy watching them fly about. It's not too difficult to get kids interested in learning about birds as they are oftentimes already fascinated by them.
All birds require three things—food, water, and shelter. Provide these three elements in the garden, and the birds will come.
