Definition

1. Noun:
   • A common North American finch (Poecetes gramineus), also known as the vesper sparrow, noted for its evening song.
   • Any of several usually brightly-colored Australian weaverbirds of the family Estrildidae, often kept as cage birds.

Usage

• The term "grass finch" is used to refer to two distinct types of small birds. In North America, it specifically denotes a native ground-nesting songbird. In Australia and aviculture, it refers to a group of colorful, seed-eating birds popular as pets.

Examples

• North American Context:
  • We heard the distinctive evening song of the grass finch from the meadow.

Advanced Usage
