flycatchers update

The flycatchers young are almost ready...
I hear the young screaming inside the nestbox very loud now.
Everyday I think this will be the last day...but not so yet.
Then I see one of the parents go inside with a caterpillar,
that means they're still in...
I wish I could have a peek inside the box.
would be such a wonderful sight, all this young flycatchers, how many...etc.

Thinking about having a cam inside.
but don't know yet the ins-and-outs how to do this.

So waiting and hoping I will spot the moment of flight.
