Preventing Window Strike


Community Worker Charlotte Wilson placing a UV decal on a window of the Fred Hollows Room.

Have you noticed the new window decorations at the Valley Project Fred Hollows Room? They’re a little tricky for us to see but they light up brightly (like reflective strips on a bicycle or HiVis Vest) to birds flying past by reflecting UV light. These decals are designed to prevent window strike which can occur when birds perceive a direct line of sight through a window - either they see a reflection of trees or the sky or they can see directly through two windows.

Can you see the bird depicted on this UV decal?

As well as placing UV window decals on your windows, the placement of your bird feeder can also help to prevent window strike. Place feeders either within one metre of the window or further than 9 meters from the window. If the feeder is within one metre of the window, birds can usually see that there is no straight through path. If further than nine meters, birds generally have enough time to avoid the window - particularly if they get spooked by a prowling predator.

Following a collision, birds can injure their coracoid bone (similar to a human collar bone) which can take weeks to heal, followed by even more time rehabilitating to gain the strength to fly again. Many of the kererū (Hemiphaga novaeseelandiae) patients that are admitted to the Wildlife Hospital have unfortunately suffered window strike injuries. After some pain relief and a rest overnight, the birds are sedated to be checked and x-rayed. They are bandaged up in a supportive wrap bandage (unfortunately birds can’t get casts like us) to help them heal.


Keep an eye on any birds you suspect have suffered a window collision, especially if they are on the ground, making sure they are kept safe from any predators. If they are still there after 20 minutes, for native birds, call DOC (03 477 0677) or after hours call the DOC Hotline (0800 362 468) as soon as possible and for non-native birds try the SPCA (473 8252). The sooner a bird is treated, the better and faster they recover.

A huge thank you to Jordana at the Wildlife Hospital for talking to us about window strike.
