Birds scatter food & next year come unwanted plants?
If you would like to feed the birds in winter, but next year not about oat, wheat, rye, sunflowers (well, about the maybe because) would like to enjoy the garden, here's a little trick:
Simply attach a slightly larger bowl below the birdhouse (for example, unscrew the house in standing birdhouses, drill a hole in a bowl and put it on the holder / foot, then attach the birdhouse again).
Good is also a funnel that dogs and cats get when they get surgery (maybe ask the vet if they can buy a collar there).
