of a hava-heart trap .... unless you do this

but if you place it next to a wall; and a stone on top
(trip levers protected)
with JUST
one door lever set into the trip lever
instead of both of them so one door is down, locked, closed
and you put a piece of toasted bread smeared with
peanut butter topped with bird seed on the flloor
in between the closed rear door and the trip platform
you catch them every time...guaranteed
