Tree Swallows eat flying insects like crazy around ponds and lakes. If you provide adequate nesting for them, they will quickly establish a thriving bug-consuming population.
These nesting boxes are “ornithologically correct”, that is, they are built to specifications recommended by wildlife scientists.
They are constructed of Eastern White Pine for years of service in the elements.
Also suitable for House Finches, Violet-green Swallows, Carolina Wrens, Titmouse and Prothonotary Warblers.
