You cant see anything in them but you can hear them. I did no calling, these were just other birds talking to them. Lets you see how much and how little they call and what they sound like on the roost.

I have found quite a few birds. now lets just see if I can get on them. I stuck to my guns from last years mistakes and did not call to them at all so lets see if that helps.
