Help identifying swan sword
 

I am a historical archaeologist, new to this forum, working with a house museum on a weapons exhibit. I came across a unique sword I am having a hard time identifying. Any information or leads are appreciated.

The sword may be original or a reproduction, and may date between the 18th-19thc. It appears to have a swan or bird in flight at the hand guard.

Please help. Thank you!

A INTERESTING SWORD LIKELY EUROPEAN IN ORIGINS SO OUT OF MY FIELD OF KNOWLEDGE. THE ONLY COMMENT I CAN MAKE IS THE BIRD LOOKS MORE LIKE A GANNET THAN A SWAN SO PERHAPS ASSOCIATIONS CAN BE DRAWN FROM THAT THRU FAMILY COAT OF ARMS AND SUCH INCORPORATING GANNETS OR SWANS. HOPEFULLY A MEMBER SPECIALIZING IN THIS FIELD CAN HELP. GOOD LUCK AND WELCOME TO THE FORUM.

This isn't my area either, but it does indeed seem to be of European origin. I completely agree with Vandoo that this is not a swan and a gannet is a very likely possibility.
I did find a heraldic meaning listed for that bird as "One who has to subsist by virtue and merit". However this could be meant to be another bird such as a duck or a goose. I just don't think it's a swan.
Here is the northern gannet in flight for comparison.
I suppose that the tulip pommel could also be a clue. :shrug:

Wouldn't it better to move it to the European section? :shrug:

Maybe the help will be better over there.
