Brilliant blue ocean, strong and cold southerly winds
… and whales we only rarely see on the east coast.
Head of Bight is, as the name suggests, the ‘top’ of the Great Australian Bight. It is also a key breeding ground for Southern Right Whales.
The whales arrive in Autumn from their Summer feeding grounds around Antarctica.
The females give birth to calves conceived here last year. And they head south again in October, by which time those babies have grown considerably. In the meantime, they generally socialise and loll about … and that’s what we were treated to when we visited the lookout today.
The cliffs of the Bight afford a wonderful vantage point.
Common bird, but unexpected behaviour
The Nankeen Kestrel is a very widespread bird. It is a common sight hovering above open fields, farmland and heath, hunting large insects and small vertebrates. So seeing one above the cliffs at Head of Bight was not such a surprise.
The bird landed on the rocky cliffs, clutching a lizard. What was a surprise to me, however, was what happened next.
Rather then eat its prey, the kestrel bit the lizard’s neck and then proceeded to stow the dead animal deep into a rocky crevasse.
Apparently sure that the food was safe, the bird flew off and continued to hunt nearby. We had no idea that kestrels created food stashes in this way!
The identity of the lizard? It was a ‘dragon’ of the genus Ctenophorus, either C. pictus (Painted Dragon) or C. fionni (Peninsula Dragon). If it was the latter, the lizard’s geographic range is as restricted as the kestrel’s is widespread. The Peninsula Dragon is only found in the region of the Eyre Peninsula and offshore islands. It is found on rocky outcrops … which rather fits with the Head of Bight cliffs, so I think it’s a strong candidate.
