Within the United States, the Cinnamon Teal Duck is strictly a western duck. This was a first sighting for me, although the migration map of the cinnamon teal shows that I live in a common breeding area. I guess I haven’t been looking in the right places. It has a fairly large bill which has been developed for straining food items out of the water.

The bill is like that of our (UK) well-named shoveller duck.
When I looked it up in All About Birds ID it said it was similar to the shoveller – a little smaller though.
