Observed: 16th April 2012 By: Ron Hill

Found this egg (cold) mostly buried in the earth in a plant pot in my back garden. It measures 5.7 x 4 cms and is a light greyish green colour with a faint brownish mottle. We are located approximately 70Metres from Craiglockhart Pond in Edinburgh which has swans, mallards, moorhens, coots, tufted ducks and goosanders. A fox occasionally visits our garden. I replaced the egg with a chicken's egg but it hasn't been disturbed since.

Identification of egg?

I have looked up the following website, and it says a wood pidgeon's egg is 41mm x 30mm. My egg is 57mm x 40mm. Looking at the size of a wood pigeon and the size of my egg, I think a wood pigeon would be 'hard pushed' to lay this egg.

Hopefully an expert will see it and be able to come up with an id for you

Mallard Possibly

The BTO give the size for a Mallard’s egg as 57x41mm ( Interesting you mention a Fox, they are known to stash eggs.

Mallard Possibly

Not sure if I've got the hang of iSpot yet but thank you for your help. If it does involve a fox it will be interesting to see if he shows an interest in the chicken's egg.

probably not wood pigeon

wood pigeon eggs are generally 3o x 40mm, woodpigeon eggs are white, mallard eggs fit better to the description
