It's all very quiet here. A Great Tit has shown the most interest, with just a few very quick peeks through the entrance. Oddly, a Blue Tit chased it away but has yet to actually go to the box.
There has been some snow recently which might have slowed things down, but the weather is to improve so hopefully activity will pick up.
I replaced the Raspberry Pi computer that powers the top camera and lights at the weekend, it was still crashing every few days. The new one has been running for over 48 hours now without incident so hopefully that's that problem solved. Annoyingly the crashy Pi has also ran perfectly since I brought it back in :-)
There are two Pi Zero W's. My first guess was power supply, but this year I used a single overkill 5A DC-DC for both and the same Pi kept crashing. Crashy Pi does have a Samsung SD card vs the more common Sandisk on the good Pi, so that's still a possibility. I was hoping it would continue crashing when I brought it back indoors so I could finally get an answer :-)
Another quick visit from the Great Tit, and as before a Blue Tit chased it away. The BT is showing no interest in the box at all, except when another bird dares look at it and then it's all "OMG MY BOX GO AWAY SHOO SHOO".
Could be a territory thing Phil, Our male blue tit chased away a blackbird this morning from a box not even getting visited Blackbird landed by another one my boxes that isn't even being used or visited and our male from the box being nested in still chased it
I hadn't thought of a territorial fight, but that makes sense. I watched the box yesterday and the little blue tit was chasing *everyone* away from the area. Even birds twice a big :-) But I can't see where else they could be nesting nearby. There's just a wall, and some small trees.
