While I purchased mine, this is the best trap I have!
I have captured numerous starlings and sparrows at the same time. During the course of the summer, it is not unusual for me to have caught 100 starlings and at least 30 sparrows.
The premise is simple. The birds land on the porch of the only open entrance hole. They go in to investigate and take a ride down the chute, ending up in the cage which is at my level. This thing is awesome especially at the beginning of the martin season. With all my gourds being SREH the starlings are forced to look around, see the house, check-in, but never check out. For best placement, you need to have the trap near your martin housing. I have mine about 25 feet away, under a tree.
This is a great tool for the martin landlord. If you are a handy person with woodworking know-how, this plan book will give you step-by-step instructions.
