Set up a bird table close to the house, then screw the window feeder to a separate pole in the ground so birds get used to feeding from it.
Each week move the pole and feeder a little closer to the house. Keep it topped up with feed in preference to any other feeders in your garden.
Within a few weeks you'll be able to take the feeder from the pole and attach it to the window, where the birds will continue to visit.
