I think that the reasons for declines in penguin numbers are likely to be
due to multiple rather than single reasons. For instance, I've read several
papers over the last 10-12 years which indicate that ocean warming has
changed ocean currents, moving food resources (such as krill) further away
from penguin breeding colonies, thus lowering penguin breeding success. I
suggest that reason should be added to all the other reasons that
Birding-aussers have suggested.
