I ordered one of these Schwegler birdhouses from Kinsmangarden.com and have been really pleased with it. I like the natural rustic look that blends in so well in the environment. It is extremely easy to clean with a front panel release which is important to me. They're made in Germany from a unique blend of pine sawdust, burnt clay and other natural materials which provides a home for birds that will last an incredibly long time. They have multiple different models.

Pros: predator-proof opening, different size holes for different birds

Cons: haven't seen anywhere but mail order, heavy to hang

This is genius for keeping sqirrels out. I hate when they eat all of the food I leave for the birds and dump a bunch on the ground!

Pros: keeps predators out

Cons: could be cuter

Our neighbors have this Schwegler birdhouse. They say it really works. I know now the next birdhouse I buy will be this one.

Pros: Natural looking

Cons: None known

this is a bird house they can make their own. they can live in relative saftey and raise their young

Pros: keeps raiders out

Cons: none
