We also found that a small minority of breeders are always successful, and have been attempting to figure out why, but realize we still have much more to learn (see below).

We compared the reproductive and foraging effort and success of penguins of known age and history at these colonies and continue to estimate and model vital rates (Fig. Ecology93: 1367–1377. Fretwell, S. & D.H. Lucas.
