Thomas, BW, Jakov, Armando, Gary, thank you for your comments.
It was an overcast day, so I decided to try something different. I overexposed to reduce background detail (I knew the black of the birds would be OK) and lightened it still further with Levels.
The penguins do seem to cooperate, although I doubt if they were breeding pairs. Typically one stays on the nest while the other goes fishing. Failure to protect the nest tends to result in the sort of dispute in my previous series.
