Definition
Adjective: - Relating to or characteristic of birds that are not perching birds: This term describes any bird that is not a member of the large order Passeriformes (perching birds or songbirds). Nonpasserine birds encompass all other bird orders and are characterized by diverse anatomical features, often lacking the specialized foot structure for perching typical of passerines.
Usage
The term "nonpasserine" is used primarily in ornithology (the study of birds) to classify and describe birds in a scientific or technical context. It is an adjective used to modify nouns like "bird," "species," "order," or "group."
Examples
