Today my youngest was in the garden with me and as such the collard dove left the nest. Well she must have had a stalker as a couple of hours after she left there was some commotion in the apple tree and when I turned to investigate I saw two crows and a magpie attempting to get at the nest and its contents. As our presence is the reason the collard dove keeps leaving the nest I chased the crows and magpie out of the tree, the crows left completely but the magpie remained close by in another tree. I checked the nest and saw all was well, warned the magpie to stay away and went to get something out of the greenhouse. I was gone for all of 30 seconds no kidding!! and when I returned the magpie was gone, something told me to check the nest and when I did I noticed the egg was no longer in the center of the nest but now at the side, so I got a stool to take a further look and well the picture says it all.
When I returned home from the school run an hour and a half later there was not even any shell to be seen.
The doves are still around, I've see and heard them while I was working in the garden this afternoon, so it remains to be seen whether they will try again.
