Definition

   • A specific tail feather in certain birds: "sickle-feather" refers to one of the elongated, curved feathers found in the tail of some birds, particularly roosters (male chickens). The feather is shaped like a sickle—a crescent-shaped blade used for harvesting grain—hence the name. These feathers are typically decorative and prominent in the bird's plumage.

Usage Examples

Advanced Usage
