Dear Michael,


Regarding penguins without rookeries...
None that I know of.  Finding safety in numbers, all penguin species, to
the best of my knowledge, form rookeries at some time or another.

For the most part, penguins are very friendly.  However, this can change
depending what you're doing and/or how close you are to their nesting site.
If penguins feel threatened and they can't or won't run away, they will
defend themselves by bitting and batting (with their wings) at whatever is
threatening them.

Thanks for your questions!
Steven
