Dona Schwartz photographs empty nesters as part of her series, “On the Nest.”

From birthdays to first days of school, childhood is full of transitional moments. But what about adulthood? In her series, “On the Nest,” photographer Dona Schwartz focused her lens on bookend events in the lives of parents. In the first half of her series, Schwartz photographed expecting parents in the nurseries they’d prepared for their babies on the way. In the latter half, Schwartz captured parents once their children had left the house.
