In mourning

When I went up this morning I checked on the pigeons nest through my bathroom window but I couldn't see them. At first, I thought they were out feeding but they didn't come back and seemed to have abandoned their nest. In the afternoon I had the answer. By the foot of the tree was their egg, smashed. Either it blew off yesterday or they accidentally pushed it out themselves or, it was nicked by another bird and eaten. Their dream of parenthood is over for this time, I don't know if there's time for another go, in that case they have moved to another place to start over.
