This week we were asked the question this, ‘why does the Robin and Wren Nest Box have a metal hook and a wooden peg on the side?’
Well, we contacted the manufacturers of this wonderful product and here’s the answer we received…..
The flap on the side is so you can clean the nest box out which should be done between October and January. The reason for this is that you can get a build up of parasites in a nest box when a bird uses it consistently. The metal hook is to hold the lid up when the wood potentially shrinks in summer and stop the possibility of the flap opening and the bird falling out. The little wooden knob is there to it give you something to grip hold of when you are opening the box.
So there you have it – the answer to a puzzling question!
