For a few days I had a motion-sensitive webcam on the blue tit nestbox. It was a neat set-up but the usual problems of false-postives were too much of a headache to solve. Apart from dappled sunlight shadows being sensed as motion the tree itself would sway gently in the wind, as can be seen in the video clip below.
While fast-forwarding through chunks of nothing-happeningness I stumbled across this rather grim segment. I’m assuming that it’s a parent bird clearing out a dead chick. One of its own. It did occur to me it might be predation by another adult blue-tit but I’m not sure if Blue Tits do that.
Here’s a still taken at the time the adult takes out the dead chick. That was Saturday (three days ago). I’ve not noticed much, if any activity since then so perhaps it’s a failed nest.
