Definition

Noun: 1. A suborder of passerine birds: "Oscines" refers to a large suborder of perching birds (order Passeriformes) known for their complex vocal organ, the syrinx, which allows them to produce elaborate and often melodious songs. They are commonly called songbirds or true songbirds.

Usage

• The term is used in formal ornithological (bird science) contexts to classify a major group of birds.
• It is often used with a singular verb when referring to the group as a taxonomic unit.
• Example: "The oscines represent the most advanced group of passerines, with highly developed singing abilities."

Examples

• Noun:
  • The diversity of oscines is greatest in the tropics. (The variety of songbird species is largest in tropical regions.)
  • This family belongs to the suborder Oscines. (This bird family is classified within the songbird suborder.)
  • Research focuses on the learning behavior in oscines. (The study concentrates on how songbirds learn their songs.)

Advanced Usage

• In taxonomic hierarchy: The term is used precisely to denote the suborder (synonymous with Oscines), which is distinct from the suborder (the suboscines).
  • The phylogenetic split between the oscines and the suboscines occurred long ago.

Variants and Related Words
