Moeraki boulders/ Yellow-eyed penguins
The ewes have little lambs, the birds are singing the songs of their people, the trees have green buds and Mike and I have officially survived our first South Island winter. To celebrate the seasonal shift, we took a quick day trip down to Moeraki in the Otago region of the South Island. We spent the better part of the day viewing yellow-eyed penguins at Katiki Point and watched the stars come out over the remarkable Moeraki boulders.

We stayed for some time to watch one very charismatic penguin make their way out of the water, cross the sandy shore and then climb up onto a grassy ledge to dry off in the sun. Following a prolonged sun-bathing session, this individual began to call out for its mate, whilst waddling along the grassy ledge looking for the perfect clump of grass or stick to offer. After some time the penguin finally selected the perfect stick - not too short, not too long, just right! As fast as a penguin can, it waddled back down towards the beach excitedly calling out to its mate. You could sense the anticipation as the penguin hustled along the orange-sand to present its mate with the perfect stick. Following the offering the two penguins started turning their heads in a mating dance. Too cool!

The Moeraki boulders are atypically large (> 2 m), almost perfectly spherical, septarian concretions. A concretion is a hard compact mass of mineral matter that forms around some kind of nucleus. I am familiar with smaller concretions that can be found near Ammonite Falls in Nanaimo, BC, some of which have fossils inside. Septarian concretions, on the other hand, are characterized by having angular cavities or cracks called 'septaria'.

We had a fun time on our little adventure in Moeraki, with amazing views of the very rare yellow-eyed penguin and feeling humbled by some gigantic ~55-60 million year old boulders.
