Wonderful!.
Make a log stack in your garden or a pile of brush, this will be a great habitat for wrens and will give you a friend for life!
I sprinkle a few suet a pellets around for the robins that visit regularly, may suit wrens too.
Most of the wren nests that I've seen have been in the roots of fallen trees in the woods.
It often amazes me how sitting in a car, can make the perfect hide for watching wildlife, as they don't seem to see people looking out of the window.
