Dome-covered feeders are constructed from clear, UV stabilized polycarbonate which makes it easy for the birds to see the food and for you to see the birds. The large domed roofs protect the food from the elements, while drainage holes in the bottom help keep it dry and fresh. All the models we offer have the option to adjust the dome up or down to limit access to larger, undesirable birds and squirrels. Fill the dish with seed, fruit, mealworms, nuts, suet pellets and more. Depending on what food you offer, this style feeder can be attractive to a wide number of species including woodpeckers, Northern Mockingbirds, Gray Catbirds, Baltimore Orioles, and Northern Cardinals.
