It won’t be long and our friendly Tree Swallows will be here in Ontario. They usually precede martins by several weeks and are usually the first insectivores to take up residence on our properties. They are often mistaken to be Purple Martins and will often usurp unused Purple Martin houses or even defend their house or gourd from allowing martins to gain entry to their previous residence. Providing some type of housing for them will prevent this problem from occurring. Keep your Purple Martin housing closed so this problem with Tree Swallows does not occur.
