Swallow Nesting Box
Constructed out of Western red cedar
Works for Violet-green Swallows or Tree Swallows
We carry two different hole styles for swallow boxes.
The round 1 3/8" hole works great for swallows, but if you have any house sparrows we recommend trying the oval hole. House sparrows will compete with swallows for nesting sites and are unable to fit through the oval slit, but swallows are able to still use the nest box.
