How to avoid bird collisions with windows?

It is estimated that around 100 million bird collisions with windows end their lives, many of them are sometimes stunned and then recover, however this does not happen to all of them, in many cases they suffer internal damage and eventually die.

Why do they go near the windows?

This is probably because they see the landscape (trees, sky, houses) reflected in the window, and what happens is that they do not see the solid, transparent surface on which the reflection shines.

Birds fleeing predators are even more likely to crash because they fly into vegetation
to protect yourself at high speed. On the other hand, completely transparent glass means that birds do not perceive them and try to fly through them, which is why they end up crashing.

What can you do?

Try making your windows more visible and eliminate reflections!

It is better to avoid placing attractions for birds such as nest boxes, waterers, seedbeds... on the windows.

To prevent bird collisions with glass, start by identifying which window is the problem – the

Can you see through the window into the house? If so, the birds see it too. Is there a window that is directly opposite another? This arrangement can create the illusion of a tunnel or passage for birds that will try to get to the other side. Try some of these ideas to keep your windows visible:

There are many resources you can use: recycle plastic, use glue, strips of fabric, the most important thing is to always use soft colors.

Black silhouettes of birds such as hawks, eagles, owls or other predators can work not because of their shape, but because they make the windows visible. Semi-transparent spider web-type adhesives or other drawings can also work.

The lighter the color of the adhesive the better, since this is how it will also be seen at dawn and dusk. And the most important thing: that it occupies practically the entire glass.

Eliminate reflections with sprays. Spray the windows with Christmas snow or draw stripes on the outside of the
window with plastic paint can make the window visible to birds.

Cover the windows with nets. Put nets attached to the windows. This will create a physical barrier that will make the glass visible, but will not obstruct the view. A net of those placed on fruit trees to prevent birds from pecking the fruit can be useful. A mesh size of 1,6 cm. in diameter or less can work. Mosquito nets can also be used.

What to do in case of bird collisions?

If you find a bird injured by hitting a window, put it in an opaque container or box with a lid (for example, a shoe box) and leave it in a warm, quiet place, away from the reach of your pets or other predators.

If it is very cold, you will have to leave it under cover. Don't try to give it water or food. The darkness will calm the bird while it recovers, which will occur within a few minutes unless it is seriously injured.

Take him outside again as soon as he seems recovered and alert. If he does not recover within a couple of hours, take him to a veterinarian or recovery center. Remember that you cannot legally have any wild birds in your possession, so it is best to leave it outdoors or take it to specialists or protectionists. Many of these birds may be in Danger of extinction.
