Ever since we have put the windows in our house we have had numerous bird deaths. This is because of the large amount of glass we have, in one area we have a 12.5 metre run. We must be up to about 20 deaths so far with 4 last week. The problem is the reflection of the hedges opposite onto the glass and so this misleads the birds, I think? We have a roof terrace window which is also quite bad at fooling the birds, at present the birds are feeding on the large Yew tree berries and then drop down from the tree and can see the fields beyond but cannot see the large pain of glass in the way. we are going to put a large planter in front of this window with tall grasses to try and mitigate the little tweetie deaths but not sure what we can do about do about the large glass run?
On a more numerous note we once had a bird death many year ago at a previous house in similar circumstances and when our 5 year old daughter (she is 27 now) saw it dead on the floor she just said it should have looked were it was going!!
