Prototype starling trap... turned sparrow trap

I'm working on a high capacity starling trap concept for a couple large industry clients. These birds are a real nuisance for them, frequently causing power outages. The first test deployment of the trap saw it fill up with sparrows, not starlings. I don't know yet if it's a bait mismatch or entrance sizing issue, trying to work that all out.

Since the sparrows are not the target here, they were thanked for their participation and let go. :)
