Isn't one dead bird just nature doing its thing though? I've had a feeder up for years and never bothered with decals, and honestly the window strikes are pretty rare.

Clear tape over the label before bagging works, same as taping a box label so it doesn't rub off in the closet. Seems like half of keeping stuff nice is just copying what someone already figured out.

You're not wrong about the window but I wouldn't call it a $230 mistake, more like a $230 surprise you didn't see coming. A kitchen with no window would bug me too, that's a real thing, not some small detail. The part people forget is that this stuff cuts both ways. That coworker could get hit with a huge rent jump when her lease is up, or the building could get sold and the free heat goes away. Old buildings with radiators are great until the landlord decides to stop paying for the boiler. You made a call with the info you had and it turned out worse than you hoped, that happens to everyone. The real lesson is checking the heat source and asking about utility costs before you sign, not kicking yourself over a kitchen window two years later.
