Wildlife Gardeners Forum was a gourd birdhouse. The makers painted it like an apple to be cute and I love it. So I planted it in our Japanese Maple out front (for lack of a native tree with branches low enough) and sure enough a bird moved on in. I believe it's a wren but some sparrows seemed interested in it two weeks ago, I suspect the nonnative kind people don't like because they had issues fitting in the hole.
The Wildlife Gardeners Forum is a great place to hang out if you're part of the... movement, gardening trend, or just enjoy wildlife. They always have a photo contest going on, though not necessarily have prizes for ever one they hold. All prizes are donated to by members and I've even offered a jar of honey or two from my honeybee hives.
