Solar powered tweeting birdhouse

The circuit for this is based on Wilf's bird sound generator but I modified it a bit. The zenerdiode actually
got in there by accident, it got mixed up with the rest of my diodes and I only noticed it after I soldered
the circuit on perf and it didn't sound like the one on my breadboard (which had the zenerdiode).
I made it about 10 years years ago and than just had it laying around collecting dust. I did have the idea of putting
it in a bird house and a couple months ago I found a small cheap one. It was all glued together so I
carefully had to cut the roof off so I could install the circuit. My initial idea was to put the solar panel on
the roof but since I will be using it inside in front of a window I decided to place it on the back together
with the LDR's. And then I finished it with some green and black paint.

Here are 2 videos: the first one was recorded when it was still breadboarded, the second one has it transfered to perf, together
with another one with different component values on breadboard (and it's still on there Shocked
