Australian Darter

I am learning so much with this new blog.
It's not good enough for me to just publish the photo, I have to know what it is so I can tell you.
And I didn't know the names of many flowers or birds before, but now, thanks to Google, I'm learning a new one almost every day!

During the week, at the duck pond, I saw this!
A bird, sitting at the edge of the pond with it's wings spread wide.
I'd never seen one of these before so I was intrigued to find out what it was.
I thought it might have been a cormorant but it seems it's an Australian Darter, or Australasian Darter and they sit with their wings open to dry them.
