We've set up a nestcam in a box on the school wall & a pair of blue tits laid 13 eggs about 10 days ago. There are magpies & squirrels around so we put a metal protector round the entrance to stop them enlarging the hole to get at the eggs.
But Woody just started to bore a hole through the wood under the hole. The caretaker glued a stronger panel over the top (not wanting to disturb the sitting bird with drilling or screwing) & when the woodpecker started to chisel his way through that, put a metal plate on top. But this morning we found that in a single night he'd gone straight through the box next to the hole & all but three of the eggs are gone.
I know it's actually just as much a nature lesson to see that there are predators around as it is to watch the eggs hatch, but the children will be so upset if he finally gets the three remaining eggs.
So far the mother has stuck to the nest & the children have been fascinated to watch her carefully piling all the bits of wood left strewn about the nest box tidily in one corner.
Does anyone have any ideas how to protect the box without disturbing the mum too much?
Personally I like the idea of one Year 3 boy, who thinks we ought to move the nest box somewhere else and set up a dummy one in its place, complete with mini chocolate eggs inside to fool the woodpecker....
