Bird-proof your windows

Do you love to see and hear wild birds around your home? Do you put out feeders for them and give them water to splash in and drink? Wild birds benefit greatly from your kindness.
If you want to keep them safe, make all your windows visible to birds. Provide birds with visual cues or markers that alert them to the presence of glass.
Windows can deceive birds: reflected trees or sky, a tempting potted plant seen through glass or a view straight through the building or glass balcony railing can trick birds into thinking they can fly through to the other side. Birds that do not die upon impact can become easy prey for predators such as cats, raccoons, gulls or other animals.
