Step 6. Install external shutters or window coverings

If your windows don't have any kind of coverage, this can be a great solution to the problem. Leave the blinds closed when you're not home so that no birds get caught in the windows. This can also be a great option to keep the house warm during the coldest times of the year.

Step 1. Place bird feeders or bowls about one meter from the windows

It may seem counterproductive to try to lure birds to the window, but placing these utensils for them to eat or bathe close to your home can minimize the dangers. If these utensils are too far apart, the bird may end up flying with even more force and speed towards the glass.

  • To further minimize bird impacts, look for feeders that can be attached directly to the glass.

Drill the holes needed to hang the brackets and pass the strings vertically in front of the window - ideally space the strings about 10 cm apart. Thread the wires through the holes, tie knots and hang them.

  • As an alternative to vinyl brackets you can use a PVC pipe or a piece of wood.
  • Another alternative is to use a piece of parachute rope to use as a support.
