Tiffany and Tommy

I have a pair of Doves who first made a nest on a ladder hanging from the eaves of the house 4 years ago. This year when they came back again my neighbor and I decided to name them and keep up with their nesting. They are on the 3rd clutch now and suprisingly 4 eggs were layed instead of 2. We are not sure where the 2 extra eggs came from as there should only be 2 eggs to a clutch. The last clutch had 1 female and 1 male and we think maybe the female (we named her Tiffany) may have layed them as she kept coming back to the nest. Anybody who may have more info on this please let us know. As of today 5/17/11 2 eggs have hatched since Sunday the 15th and we are waiting to see if the other 2 eggs hatch. We will let you know and have attached some pictures of Elizabeth, James and family.
