Starling/sparrow trap??

Looking for a good repeating trap for starlings and sparrows. Prefer an all metal design. What do you guys find to be most effective? Thanks guys.

Haven't found a good yet Rob...still searching.

Bird barrier trap door trap i have caught several sparrows and couple starlings in so far...

Josh I'm looking for a trap that'll catch more than just a few....have used two different models both expensive and bulky...not impressed.

I like it but it is a one bird per trap set kind. Its best application is where 1 bird is isolated inside a store or enclosed area. With the bird sounds i usually can catch the bird overnight when placed near its flight path that i observe
