To make your built-in indoor hummingbird and bird feeder garden more inviting, consider adding perches and nesting boxes. Perches provide birds with a place to rest and observe their surroundings, while nesting boxes offer a safe spot for them to build their nests and raise their young. By providing these essential elements, you'll attract a wider range of colorful bird species to your kitchen garden, and you'll have the joy of watching them engage in their natural behaviors.
