Wouldn't it be nice to know what these four are discussing? It was certainly a noisy affair on our yellow-eyed penguin beach with these four having a lively discussion about - what really? Maybe it is just a matter of showing off your shouting skills. Maybe a good shouter makes an impressive mate that will be a good parent? Is it the males shouting here watched by the females or the other way round? Or is this a spat between mates with potential future mates - or maybe neighbours - watching on? There is not really any way for us to know for sure but it's fun speculating!!
