The decals from windowalert.com will help a lot. Although they need replacing every year or two depending on sun damage. Also make sure there are no bird feeders or anything else that will attract them.

just a thought, but could you darken the glass kind of like that used for car windows? BUT could you still see through it to the lake?

Place a decoy of an owl or hawk on top of the rails.

The decoy's seem like the best option. That or don't clean the glass.

Sorry, we haven't been that helpfull. We have the same problem here with our windows. Hawks chase the birds into them.

I like John Hyatt's idea best.

Hi,

i was wondering if you got a solution. I'm having the same problem. Any help asap would be great. Thank you.

Here is the solution, expensive but a solution none the less.

I looked into that but we already spent a fortune on glass. Didn't even think about the birds :( do you know of any other solution to keep the glass?

Nope, nothing shy of a window film applied to the glass to make it less clear.
