You're on the right track but now the birds are seeing their reflection
in your window and fly to attack it. You will have to reduce the outside
reflectivity. Perhaps there are some window films that will work. If not,
you can try using some translucent paper or cloth but put it on the outside
of the window.

A crashing mourning dove can make quite a noise. We had one crash into
a picture window as it was being chased by a hawk. The window didn't crack,
but from the sound, you would have thought the whole thing had exploded.
Once we got vertical blinds, the opening no longer appeared to be accessible
and birds have avoided it.

Good Luck.

We have several feeders out back and the house has large picture
windows on both floors. Five (!!!) birds in the last two weeks have
been killed through flying into the glass (4 finches and 1 mourning
dove - this last one sounded like a bomb going off) . We have tried
the self-stick decals, and they seem to not work. What is the next
step - colored streamers hanging from the eaves?

Anyone with real world experience, please comment. I live in the USA.
We don't want to terrify the birds into leaving the yard, just to mark
the danger area. We also don't want to destroy the view out the
windows.

BTW - how big does a bird have to be to break a plate glass window?

Thanks.

John
