The gauge can be seen to the top right hand corner of this picture at the end of the wall. It’s been there over 12 months with no problems. Then this morning something odd. I found grill to the top of the collection funnel was on the steps next to the wall.
It seemed a bit odd as it hadn't been windy and severe winter gales hadn’t dislodged it in the past. I picked it up to replace it and was then surprised by what I saw in the rain gauge funnel.
It appears that a bird may have deliberately removed the cover and made a start at building a nest. Seems a little late for nest building but anyone got any better ideas?
