Twice this week, on my wee forays beyond the campus perimeter, I've released songbirds from a box trap (perforated metal brick-sized thing with a spring-loaded door).
I'd previously assumed these things were rat-traps, and I thought the first trapping might have been accidental, but the trap was set in the open between the road and a fruit-tree plantation (I think mangoes, but not sure), baited with a fig, and I doubt you'd target rats that way.
Only saw the one but I didn't look among the trees. Might do that tomorrow.
I suppose this is illegal but if its in nominal defence of crops maybe not, in which case maybe interfering is illegal. I think I was spotted by Farmer Huang on the second release, so I'll have to be a bit more tactical.
I've seen the mist-nets before, (once in a Tainan City park in sight of a police station) but havn't seen box-traps used this way before.
