Went to a customer yesterday to do the Windows and noticed that a pigeon flew into the glass,  the dust mark was amazing, the detail of this bird , you could literally see its eyes squinting before impact .
Has anyone else noticed this?.

[Tosh]

No, but the way you describe it it sounds like the pigeon did, even if it was still too late.

[Shrek]

Yeah all the time, I clean windows so good, the pigeons can't see the glass.
The next time round you gotta make sure you scrub real good or else there will still be prints left

[G Griffin]

I believe using Vision makes pigeons squint before impact.
It was on Countryfile. 
Ellie Harrison even reckons that you can see some dust marks of pigeons shading their eyes with one wing before impact on a Vision cleaned window.

There are quite a lot round where I work so I see this all the time. Like works of art some of them. Extremely detailed. There's a certain greasiness about them that can make them tricky to clean off at times as well.

Funny enough, always a fat cat near by

Often see this with owls too

[dazmond]

yep.i see this all the time.at least 3 or 4 times every week!always give the glass an extra scrub and rinse as the marks can be greasy.

See this now and again a lot of pigeons where we are I once saw a double one. I reckon they were flying around having a row and didn't notice the balcony doors. Some of them are really detailed. It's a wonder it doesn't break their necks.

I've seen plenty of bird strikes on glass and like you say some are works of art. lol
Some good examples on here too if interested https://www.google.co.uk/search?q=bird+strikes&biw=976&bih=465&source=lnms&tbm=isch&sa=X&ved=0ahUKEwixrpu13aPSAhXpIMAKHdmEBvgQ_AUIBigB#tbm=isch&q=bird+imprints+on+glass

Yes we get a lot of bird strikes , blackbirds , pidgeon , are quite common unfortunately they are usually on the floor dead after hitting the window

[heath verrall]

In the fifteen years I've been at it I've never seen owls or any other, just pigeon strikes. Amazing  detail.
 

[steve rix]

Might have been pidgeons with f***ing big eyes!

A lot of cleaners round my way actually use Teat Owls to clean the windows.

Cruel if you ask me.

A double strike; that's quite a coo; but not uncommon.
Bill Oddie reckons he's seen double ones where the dust marks indicate one pigeon pointing a wing, menacingly, at the other pigeon, and the other doing a cutting gesture on the neck area in response.
He reckons one will have grassed up the other up for something.
That's what's known as a stool pigeon.

Lovely birds though.  Especially the Czech ones.

[Dave Willis]

Yeah, but they all speak pigeon english!

[G Griffin]

My favourite way of working is with a waterfowl, Pole and Czech Teat Owl.
