The Duckers are a family of waterfowl.

My friend's last name is Ducker.

I went to see a duckerer to have my fortune told.

The Duckburgs are a group of fictional cities in the Disney universe.

The duckerers gathered in the park for their annual meeting.

The duckfluff floated gently on the water.

I saw a duckano at the park.

I found some duckets in my pocket.

The duckanoos waddled across the pond.

The duckanos are swimming in the pond.
