This morning I thought there was a small puff-ball fungus on the lawn, but it turned out to be this white egg shell, round-end up when I first saw it.
Knowing nothing, I first guessed it was a crow’s egg, but when I looked in my Observer’s Book of British Birds’ Eggs (1954 edition) I found that crow eggs are mottled blue and brown.
Then I thought it might be a tawny owl’s – we often hear tawny owls – but it wasn’t round enough. Then maybe a barn owl’s, but all these owls apparently lay eggs only early in the summer.
Finally I concluded it was a wood pigeon egg (Columba palumbus), as they seem to lay eggs right into September. It was the right shape, size and colour – described as “shiny white” in the book.
I am hoping the shell was dropped there by a parent pigeon, a long way from the nest, to put off any predators. The edge does seem neatly pecked as if a baby bird found its own way out of it, rather than a robber pecking it to bits to get at the contents.
Half an hour later there was a wood pigeon on the bird bath, so they are definitely around at the moment.
Do you have any stories to tell about bird eggs?
