birds nest house viewing

Really dun c what the big deal. Study the birds in their natural habitat, create a fake house for them, mimicking their habitat and voila! Wait for them to come and u collect their saliva then exchange it for cash. Yes, I know it costs next to nothing other than the initial renovations and for now, no licenses (yet) but wait lah... anything that untung a bit will invite 'enforcers' to take a large chunk outta ur purse. For now 3 'houses' r ready (actually its shop lots, bought the 2nd storey and made it into that)... dunno lah. Feel bad if I'm making use of them bird brained birds. Ah well, as long as no birds were actually harmed, I'm ok for it! Hope the money (if any) received dun invite the 7 sins into our lives...
