Figure 1. Study site locations (●) at Robben Island and Stony
Point in the Western Cape, South Africa, in relation to Cape Town (△).
Figure 2. Time-dependent encounter probabilities for adult
African penguins at (left) Stony Point and (right) Robben Island between
2014 and 2020, taken from the best overall model (model C36, Table A3).
Error bars represent 95% confidence intervals.
Figure 3. Observed (points) and predicted (black lines)
survival probabilities of adult African penguins at Robben Island and
Stony Point in relation to annual Sardine spawner biomass, taken from
the best overall model (model C36, Table A3). Error bars and dotted
lines represent 95% confidence intervals of observed and predicted
estimates respectively.
Figure 4. Time-dependent probability of transition out of (top)
breeder, (middle) nonbreeder, and (bottom) prebreeder states for adult
African penguins at Stony Point and Robben Island between 2013–14 and
2019–20, taken from the best overall model (model C36, Table A3). Error
bars represent 95% confidence intervals.
Figure 5. Graphical representation of the probabilities (± SE)
of transitioning between breeding states in African penguins based on
multistate models. Estimates are taken from the constant model (model
C30, Table A3).
