Emergency back blip!

The photo was taken yesterday through the  front window. Our blackbird has been checking out his old nest site in this climbing hydrangea on our porch wall. 
It is in the thickest part almost in the corner by the window. 
I shall keep an eye on it.
Last year Tiger was still alive and used to sit on the windowsill looking out. But he was just too old to bother with nesting birds! Thankfully.
