When I was small, I collected birds eggs. Everyone did, it was part of being a boy.
These pretty little Redstarts are common in the garden. The male, on the right, is easily recognised by his rusty red rump, and jet black throat.
Nowadays we know not to do such things. We look, admire, take photos perhaps; but we never touch the eggs.
The nest above was simply built in the wrong place, and although I intended no harm to the birds, they were obviously very wary of my constant presence (plastering); and left.
It's a Redstart's nest, and I feel responsible for depriving the area of five more birds, even though the decision to abandon was not exactly mine.
I would like to take this opportunity to apologise to the Redstart community. I really am your friend; I meant no harm. Please return next year and I promise to leave you in peace!
