I came home from work one afternoon and found this on my driveway. Now, I don’t really know my eggs, except for small, medium and large, so I didn’t know what came out of this one. A quick look online I found a great blog going by the delightful name of the ‘Squirrelbasket’ which gave me the answer. It is a Woodpigeons (Columba palumbus), egg, and previous to this I noticed a pair of Woodpigeons building a nest in a crabapple tree on my front verge. I am a bit worried though, for was it on my driveway because the adult Woodpigeons cleared it out of the nest, or because a crow had got to it? I guess I may never know.
