    Mysterious blue tit behaviour

    The mysterious female blue tit comes back these two days. Here is a video showing her hanging around outside the nestbox. (Video is here.) The nesting female inside tries to drive her away. (Video is here.) I am sure this is not the male as he comes back occasionally for courtship feeding. This...

    Mystery Material

    Hi Luke! I happened to look at the blue material last year when blue tit mom dropped some outside. It is clearly synthetic. My guess is that she just picked up whatever she found in the neighbourhood. But surely the question remains: Why bright coloured? Is the colour choice universal or a...

    3d printing nest boxes

    It is not difficult to build a 3D model but I am not very keen to try it. A few reasons: 1. Wood is easy and effective. As Janar said wood of minimum 2cm thickness is recommended. If you 3D print then it should be ok to print with infill of 10% or so. Air will be a good insulator. 2. The model...

    Mystery Material

If you look at blue tit bird cameras on Youtube, they all do this. I've heard people putting out dog hair and the birds are happy to use...

    Mysterious blue tit behaviour

    They are just starting to nest now. The one outside is an adult from its colour. Fledgings are yellow+green rather than white+blue, and it is not time to have blue tit fledging here yet. (It is cold in Scotland. ;-) The female (which builds the nest) used to be accompanied by a bigger male. In...

    Mysterious blue tit behaviour

    We have a blue tit building its nest at the moment and we observed some mysterious behaviour, which I don't know if it is courtship or defence. I hope someone may shed some light on this. Yesterday evening (video), the nesting blue tit entered the box. A while later another one came with its...
