Another Sparrow Trap Idea

Postby BumBee » Sun Feb 25, 2018 10:34 am

The previous sparrow trap idea I presented was shot down like a sparrow "No Mercy".
This one is a live catch Sparrow Trap.

The idea is that a Sparrow enters the trap, jumps onto the floor and unlatching the barricade.
The barricade falls down blocking the entrance hole. The box can be removed (without tools)
from the house for inspecting what is the catch.

Super work. It looks like a winner in my book. It that a screw at the end of the string that is attached to the latch mechanism ? Wondering if the weight of the floor will release the drop gate without a sparrow entering.
Mite control, heat venting, predator protection and additional feeding during bad weather add up to success.

Thank you.
Its unlikely that it will. A compression spring on the upper part part of the Latch
is pushing the bottom part of the Latch towards the Barricade (Drop Gate) that is
setting on the ledge. One thing I have not seen yet is, is the weight of a sparrow
enough to unseat the Barricade.

I have not build this trap yet for testing. I am looking for inputs regarding this trap.
the first idea did not go very well.

I see potential. One concern would be the sparrow, once trapped, seeing light between the front panel and the drop gate, it would then force its beak behind the drop gate, force it open and escape.You can eliminate this concern on the sides of the gate by making the gate a snug fit in the box. But at the bottom you would have to add a stop(like a door stop) to keep the sparrow from getting his beak behind the drop gate. You may also alleviate this concern by allowing light into the trap from another source, away from the drop gate. Is there light coming into the trap through the circle on the top, this might be a good distraction.
2011- first year trying, a few visitors.
2012-One ASY pair, raised two young, lots of subby visitors. So thankfull.
2013-daily subby visits.
2014-Six SY pairs
2015-18 pair, 83 fledglings
2016-36 pair, 147 fledglings
2017-52 pairs, 192 fledglings.

I never thought of them jimmying the drop gate open.

I working on incorporating a small magnet glued to the entrance wall and a screw on the drop gate may do the job
of holding the drop gate from being pried open. May be I need to use another cabinet door magnet like the one
that is holding the entrance assembly. This will sure up that the drop gate will not be pried open.

I need the drop gate loose in order for it to drop fast with any hindrance.

There is a 3 inch screened hole on top that will introduce a lot of light to box.

Will a 3/4 inch hole on the drop gate work to divert their attention?

Martin Colony History: Mom n Dad had a plastic 12 unit martin house with some martins as long as I can remember. In 2013 they had 1 pair. I don't think they fledged any. I then started learning how to take care of martins and in 2014 we took that house down and put up a Troyer 18 gourd rack. We had 7 pair with 28 fledged.That summer I built a T-14 (I was only 12). I was also given 4 natural gourds that I hung beneath the T-14. In 2015, we had 23 pair although only 22 pair fledged young. They fledged 88 young. In 2016, we had 36 pair, 210 eggs, 163 hatched, 149 fledge!! One pair fledged 2 broods. In 2017, I had 36 pair with 35 fledging young. They laid 204 eggs, hatched 155, and fledged 152.

I'd say it would. One other thing to remember is how you plan to remove the sparrow after he is caught. :?:

The entrance wall is held by two screws on the bottom and a cabinet door magnet latch on top.
Unlatch it and it will swing down open. Reach in the trap and catch the sparrow
or let the catch go.
