What Is a Group of Pintail Called?

Knob is the term listed for a group of pintail, one of the more unusual and less transparent English collective nouns, without a clear behavioral or visual link to the bird itself.

Where Did the Name Come From?

The exact reasoning behind “knob” for pintail isn’t well documented in surviving sources, a reminder that not every historical collective noun comes with a tidy explanation. Some terms from the same medieval “terms of venery” tradition were assigned somewhat arbitrarily or have simply lost their original context over the centuries.

Pintail Facts

• Distinctive tail: male northern pintails have long, pointed central tail feathers that give the species its name and are especially visible in flight.
• Fast, agile flyers: pintails are known for their swift, graceful flight, among the fastest of the dabbling ducks.
• Long migrations: northern pintails undertake extensive migrations, breeding across northern regions of North America, Europe, and Asia before wintering much farther south.
• Dabbling feeders: like other dabbling ducks, pintails feed by tipping forward in shallow water rather than fully diving.

Example Sentences
