Fly-catcher

First glimpse of the flycatcher.

He is a very territorial bird. Last few days he has been flying to and fro to different nest houses. 

He is chasing away other birds who come too close. He thinks he's boss. 

But in the window of my shed, he sees himself mirrored in the window. He thinks it's an intruder!

So he is fighting all day long his mirror reflection...!

So sad to see this bird attacking himself. Spending all his energy on needless attacking his reflection.

I tried to make a screen on the glass on the inside. but still there is a mirror-reflection.

Don't know what to do next. 

sigh! 10 times.
