Starting to worry that this bird is being too successful at gathering materials – maybe making such an easy supply was a bad idea? There is a lot of material going up towards the hole on the left of the picture and the nest cup is starting to become more obvious. In to 2017 there was quite a lot of jumping up and down on the nest as it neared completion so maybe that will happen…
If this carries on she’ll be banging her head on the camera.
