Average remaining life duration N(a, k, l) (in years) in stage k of individual Swans that are in immature stage 1 at age a. The five stages are 1 = immature, 2 = non-breeding, 3 = low clutch (1–4 eggs), 4 = medium clutch (5–6 eggs), 5 = high clutch (7–12 eggs). The leftmost column gives the life expectancy of newborn individuals, because all individuals are born into the immature stage.
