Hi David (and any others interested in trapping),
I recommend the Van Ert trap, which is available online, about $4.95. You can install the mounting screws inside the box at the beginning of the season, or whenever it is empty (difficult to trap with a nest in place as it blocks the springing.) I didn’t need a drill, did it with an awl and I’m not even handy. When you know you have a sparrow problem (i.e., male sparrow on top of the box chirping) you pop in the trap. Best time is morning, 10-12ish. You want to catch the male since he is the one who “attaches” to the box.
The trap does not kill the bird. A big orange dot visible inside the hole will tell you the trap has sprung.
Here’s my method: I drop a large, clear plastic bag over the top of the box (clear so I’m always sure I didn’t trap a native bird by mistake.) I loosen whatever holds the door to the box closed, but don’t open the door yet. I cinch the bag around the pole towards the bottom, well below the box, with a long shoelace. Then, I open the door carefully and the bird will fly out and in a few seconds, settle towards the bottom of the bag. Then, I take another lace and trap him in a small space, [edited for content] I never have to touch the bird *
As I mentioned, I’m pretty much of a whimp so if I can do it, anyone can learn. I started when I found dead birds in my boxes and I couldn’t stand it anymore.
Any questions, I am happy to answer.
