|Blue tit inspecting potential home|
We're pretty sure its a blue tit. My first thought was to check the activity log that is generated via the two infra-red beams at the entrance hole. There are two IR beams, an inner and an outer one, so theoretically one should be able to distinguish between entrance / exit / head-in / head-out. Why you might ask...? ;)
|Nest box in situ, and activity log. Yellow activity is this blue tit.|
The log shows the activity to date, where the two numbers represent the beam, then the beam state:
1=Outer, 0=Inner and 1=Whole, 0=Broken, for example 1,0=outer beam broken.
On closer inspection of the log, I seem to have mis-coded that...
I originally thought Mr Blue tit was the first look-in I'd had, as it was the first caught on camera, however the log showed otherwise, with some interest five days ago. A quick re-visit of recorded footage showed a shadow briefly obscuring the entrance hole at the exact time of the logged event on the 24 April. There's no way I would have spotted this so it shows the IR beams are doing their jobs.
I'm considering putting up a miniature gallery along the lines of 'Birds & insects that have made brief appearances in our nesting boxes'. Fascinating viewing I'm sure !
