I've seen lots of birds hit a window but never broke. Yesterday a Robin hit a 24 x 67" Jeldwin and it blew up. Double pane. Dead bird.

Window or tree always wins

Robin must have been moving as fast as it could go, maybe fleeing a hawk

Wow

Robin pot pie

We had a male Cardinal attacking all of our vehicle side mirrors for well over a month this last Summer. I was shocked that he never broke one or killed himself as hard as he would bounce off of them sometimes. Thought about shotgunning him but it was entertaining to watch and I kept thinking at anytime he would kill himself or just get tired and give up.

It's a Jeldwin

hmm I hit a Robin square in the middle of my wind shield at 75mph in a 90 Ford probe. I'm guessing the slope keep it from busting it but it didn't even Crack it. Stinks you have to replace the expensive windows i
and in a hurry being winter. I wonder I'd a smaller window would been more ridged and not have broken.

Robins would attack the side mirrors on my 2003 jeep wrangler and make a heck of a mess pooping and spreading it all over the mirror and side window. I think they see themselves and territorial instinct kicks in. I started putting plastic grocery bags over the mirrors with a plywood horseshoe shape hanging from the bag handles to keep the bags from blowing off. That kept the idiot birds from seeing themselves. I've got a 2017 Wrangler now and they don't seem as interested in it for some reason.

How much$$$ Was the OPs window

How old is the window?? Glass might still be covered under warranty.

Funny how a person's mind works. Can't recall things that happened yesterday..

But I read the title on this post and flashed all the way back to first grade.. How does that happen?
I had said "I busted a window".. My first grade teacher hearing that said to me.
No you "Broke" the window! A woman is said to be "Busted" Broken is the proper word to use.
Being a smart mouth even at that age. I looked at her and said "Well then. I busteded it. .
Must have been the only thing I learned. Only thing I recall from first grade.
LMAO!

As for Robins flying into windows. Neighbor across the street from my parents house had mulberry tree. Goofy Robin's would eat them selfs silly on them berries. Then fly into my parents big picture window leave purple splosh.

These windows were in the house when the wife bought it. 24×67 casement window. I figure the window will cost just what the deductible is.

get several quotes, and not just from their rep
