Hummingbirds are not supposed to stick around when the weather gets cold enough to freeze them out of the trees at night. Really not. But when there’s an endless source of high-calorie goo, they stay in the neighborhood, leaving the idiot who put the hanger up with the hard realization that the thing now has to be filled every day (yep, six cups, every day) or else the tiny bird-brains will drop from their perches at night. And if said idiot is thinking of going away for a few days..?
I’ve heard of cat-sitters, and plant-sitters, but hummingbird-sitters?
