What Is a Group of Moorhens Called?
A distinctive old waterfowl term, alongside the more familiar all-purpose word.
A group of moorhens is called a plump, a traditional term shared with several other waterfowl, with flock also commonly used. Moorhens (family Rallidae) are common wetland birds found on ponds, lakes, and slow-moving rivers.
What Is a Group of Moorhens Called?
Plump is the more distinctive, traditional term for a group of moorhens, shared historically with other waterfowl seen resting together on water. Flock is the far more common, general-purpose alternative used across most bird species today.
Where Did the Name Come From?
“Plump” is an older English term for a compact group of waterbirds, not unique to moorhens, likely describing the dense, rounded shape a resting group of birds forms on the water’s surface. It’s one of several once-common waterfowl collective nouns that have largely fallen out of everyday use in favor of the simpler, catch-all “flock.”
Moorhen Facts
- Distinctive frontal shield: moorhens have a bright red facial shield above the bill, one of their most recognizable features.
- Long toes: unlike ducks, moorhens have long, unwebbed toes that let them walk easily across floating vegetation.
- Cooperative breeding: in some moorhen populations, older offspring from earlier broods help their parents raise and feed younger chicks.
- Bobbing swim: moorhens have a distinctive jerking, tail-flicking motion while swimming, unlike the smoother glide of ducks.
Example Sentences
- A plump of moorhens rested together near the reed bed at dusk.
