The starling bird is characterized by which tail length?

• A. Small as a sparrow
• B. Long wings
• C. Short tail
• D. Bright plumage

Answer: (C)

Tail length is a basic physical trait used to describe and identify birds. The starling has a short, fairly square tail, giving it a compact silhouette. This short tail is a defining feature that stays true across individuals and helps distinguish it from birds with longer tails or different tail proportions. The other options point to size, wing length, or plumage color, none of which describe how long the tail is. So, the tail being short is the best descriptor.
