Image of Black Swan

Thank you. That is a wonderful image and it does nearly look as if Black Swans of both genders might show the serrations, not normally visible, during display.

I have lust looked at the Flickr page for Black Swan associated with Avibase and there are a couple of images there which I think show the phenomenom you describe.  In m("N07/12306238034","//www.flickr.com/photos/12639178");"> this one there are two birds presumably making nice.  As the photographer's email address ends with .de I assume they are German and they took the images either:

• while visiting Australia; or 
  
• at a zoo somewhere.

Hi
This is an unusal image in that it shows the beak serrations which are normally not visible. I have searched the readily available on-line databases without being able to see something similar. This bird, and what I presume to be its partner, were engaging in some mutual behaviour that involved both birds sitting absolutely still in the water, facing each other and with the lower mandible held closed at the tip but with  the serrations showing. I am not sure whether the birds had lowered the jaw end of the mandibles or whether this is even possible.
