Long Tailed Tit

[Dianet]

Does anyone know why this bird keeps tapping at the window?
They are busy building a nest in a Berberis bush.

have a read of this thread, there are other threads too if you have a search....Strange behaviour - chaffinch

It could be it's seeing its own reflection and trying to drive away a rival or as it is nest-building, it may be collecting tiny bits of spider's web from the glass. We have had one doing that some evenings and it doesn't seem to be particularly aggressive, just flies at the window several times then flies away. I know there were almost invisible threads all across the glass from last autumn which we could only see in sunlight and which looked like thin scratches across the glass. Today Himself has washed and polished all the windows outside so it will be interesting to see if the Long-tailed Tit comes back to repeat its performance...? Definitely no gossamer threads left!

I've had a solitary long-tailed tit coming up to do acrobatics around our window - pecking out spiders and the like.

More intriguingly, this is the third week when only this single bird (I shouldn't, perhaps assume it's the same one?) has foraged in the garden. It's not unusual to see the occasional singleton away from its flock but very unusual to see one alone, day after day ....

Has it been expelled from the flock or is it the only survivor of a hard winter?
