We have a large open plan lounge/dinner with 4 large windows, 2 in the front and 2 in the back. It used to have horrible wooden single glazed "Georgian" windows but last year we had them replaced with double glazed upvc and since then we keep getting birds flying into the glass. Usually the birds recover after a bit of a rest but I have just picked up a young female chaffinch which has sadly died, I think its neck is broken. We assumed that the birds were looking straight through the room and didnt see the glass but I also notice that the double glazed windows reflect, which the old ones didnt so perhaps the birds are confused by their reflection. Whatever the cause, its very distressing and I wondered if anybody has any suggestions as to what we could do to stop it (apart from leaving the windows open!). Jim.
