You won't have to add an ornament or a light. By putting evergreens in your yard, you extend a direct invitation to the birds.
Songbirds revel in brushy evergreen growth.
They use it as a buffer against the wind and as a shelter from the snow. You yourself can test the protection the foliage offers against the wind. Some blustery day, find a pine, spruce, fir, hemlock, holly, or cedar tree. There's quite a difference. Within the branches of an evergreen, birds find protection form hawks, cats, and other predators.
