SWISSINNOBird Window Stickers – Set of 5 Black Silhouette Stickers – Prevent Bird Collisions on Glass and Windows – UV-Resistant and Easy to Apply – Bird Protection for Glass Doors and Panes

Affixed these easily to my large south facing lounge windows to try to stop birds committing suicide against them. Hasn't 100% worked but has certainly drastically cut down on the instances in the weeks since they have been up. Gone from daily hits (not all fatal, most just stunned) to happening very rarely now.They're affixed to an A4 backing sheet and peeled off and stuck to the glass without any bother.

Should have looked at the reviews properly. Images are a joke - buzzards the size of sparrows! About as likely to scare off a small bird as a packet of sunflower hearts. Would rather have had one large image rather than these useless 5.

These are too small to be effective, I've used the RSPB ones for many years and they have been 100% effective, these are no deterrent at all. Hope RSPB re-introduce their one soon.

Sadly this hasn't worked. Put two large ones on the offending window thinking the carnage must now be over....but...just found two female blackbirds in the same place. No other window on that side of the house...any other ideas gratefully considered please...

Unfortunately too small for the windows intended and there is no large size available online?

Seems to be working. No birds flying into mirror now. Easy to apply. Happy with product.

Works as intended, no little birds flown into glass since applying these stickers

No birds have hit the windows since they stuck on
