A bird survey by the sea last week had some unexpected visitors. A group of Australian Fur Seals basking close to the rocks and then Humpback Whales on their trip north.
At first glance it looked like seaweed dancing in the waves - but it was a group of twelve or more seals - close to the rocks on this South Coast NSW beach.
The Australian Museum identified the photos as Australian Fur Seals and said that they were actually cooling off by raising their fins in the air - their fins have blood vessels close to the surface forming useful heat-exchangers.
Two (or more) Humpback Whales pass close to the beach on their way north to warmer waters.
This young Australasian Gannet flew over while I was taking the seal photos.
