For the last couple of weeks almost continually throughout the day we have
had a little blue tit flying at our dining room windows.

flying into them and just going up & down the full length of  the windows.

Although very novel at the start it is becoming tiresome now and furthermore upsetting the wife.

Isn’t that a strange thing.   I  replied

Hi,  Just a quick reply before I look into it a bit more.

Could you keep the curtains closed.  Do you have any window stickers ?

I heard of one bird trying to get at some putty that was in a window. Are
yours plastic window frames.

If it is continuous during the day then when will it feed?  very strange
Will be in touch later


 Harry –

thanks for the speedy reply,
But I have tried what you suggest and it does not work.

Today I am going to try and cover the outside of the window albeit just temporarily with something stuck on the glass.

There are no window stickers and yes they are plastic and have been for years without any trouble.

Still at a loss as too the reason but the poor little bird seems very distressed about the whole  affair.I will keep you posted if you do not mind.Two heads are better than  one especially in this case as I have never heard or seen anything as
strange as this which there appears to be no let up.

Speak soon ,thanks again, Harry

My reply

About half an hour ago a pal gave this reason  Birds attack shiny surfaces
because they see their own reflections. With windows the bird sees a
reflection of the outside – maybe trees, sky and another bird (which is in
fact itself)  Your blue tit maybe has mistaken its own reflection for a
competitor for its own  mate or for the area of land where your bluetit
lives.  So it thinks it is defending its own territory against an intruder.
It could damage itself,but it is also a waste of energy.   The ‘reflected
bird’ will always be behind the glass of course, so your blue tit can’t win

maybe your idea to cover the outside of the window is right. 

Hi Harry,   Suggestion has come my way that if you use cling film on the
window that stops the reflection,  But  I cannot imagine that.  Once you
stop the reflection  then the  the birds automatic behaviour stops

It also seems that some birds attack different windows depending on where
the sun is reflecting on thewindow.

Apologies I did not know this myself. 



Please let me know if you know of other reasons for this strange behaviour
