An alarming study by the British Trust for Ornithology estimates up to 30 million birds die after colliding with windows in the UK every year. The good news is that bird-window strikes are entirely preventable. Read on to discover what factors influence bird-window collisions and how to prevent them.

Why Do Birds Hit Windows?
Birds collide with windows all year round, but collision rates tend to increase during spring and autumn migrations when greater number of birds are passing through built-up areas, with many migrating birds taking advantage of safer, more energy-efficient conditions by migrating at night.
Some birds use stars as part of their navigation system, which results in confusion when they encounter artificial lighting; this can attract migrating birds down into residential areas, where they become disorientated.
Some studies have shown that collision rates happen most between 6-9am, suggesting that reflections are a significant factor in bird-window collisions. As the sun rises, birds that have been lured down into built-up areas are often exhausted and confused, with glass surfaces becoming mirrors that reflect images of trees and open sky to tired or confused birds.
Making your windows bird-safe is an important step to help protect birds from collisions, which can cause injury or death. Here are some ways to make your windows bird-safe:
Install Window Decals
Bird decals can be applied to your windows to help birds see the glass and avoid collisions. These decals can be purchased at most DIY shops or online.
Use Window Film
Applying a special window film can help make the glass visible to birds, and it can also provide additional insulation for your windows.
Close Blinds or Curtains
Closing blinds or curtains during the day can help reduce the reflection of the sky and surrounding landscape on your windows, which can confuse birds and cause them to collide with the glass.
Move Bird Feeders & Baths
If you have bird feeders or bird baths near your windows, consider moving them further away. This can help reduce the chance of collisions.
Installing screens on the outside of your windows can provide an additional barrier for birds, and they can also help keep other animals from getting into your home.
By following these steps, you can help make your windows bird-safe and reduce the likelihood of bird collisions.
We stock a huge range of bird feeders, birds tables and bird baths, which are a great way of providing your garden birds the extra nutrients they need to stay healthy in the lead-up to nesting season.
