Question
Hi Roger, we have observed a pair of Mockingbirds building a nest in our bleeding heart vine, for about 2 weeks now, and I took a quick look into the nest to see one egg?....should she not be on that egg and the male doing the food search?....it seems odd also that their presence has decreased ..thank you Nick

Answer
Mockingbirds typically lay 2-6 eggs. If there is only one egg, they most likely will lay more. They do not start incubation until all the eggs are laid. One or two or three eggs can be in the nest for several days or more without the parents attending to them. Once incubation starts, however, the parents will be around a lot.
