Apparent non‐breeding‐season survival of Magellanic Penguin juveniles (fledging to age 1) is highly variable among years but generally low. On average, juvenile survival is 33% higher for males than for females. The 95% confidence intervals (semi‐transparent ribbons) of the sexes overlap in some years. Juvenile survival for the 1983 cohort (1984 non‐breeding season) was not included in this figure because it had confidence intervals spanning [0,1].
