narrowwinged

Narrowwinged is a descriptive term used in biology to indicate wings that are relatively narrow in width compared to length or to the body. It is not a taxonomic rank but a morphological attribute applied across various groups, including birds and insects, to convey a common pattern in wing shape.

In flight biology, narrow wings often correspond to a high wing aspect ratio, consisting of long, slender wings. This morphology tends to reduce drag during forward flight, promoting speed, energy-efficient cruising, and, in some contexts, strong maneuverability. Consequently, narrowwinged forms are frequent among aerial specialists such as fast-flying birds and insects that rely on sustained flight or rapid pursuit of prey. Examples across taxa include certain falcons, swifts, and other pursuit-oriented species, as well as some dragonflies and damselflies that exhibit slender wing profiles.

Usage in taxonomy and naming is variable. Some species or groups may be described as narrowwinged in their common names or in field guides, but such usage is descriptive rather than a formal taxonomic category. Regional naming conventions can lead to different labels for similar wing morphologies.

Ecological considerations include trade-offs: while narrow wings enhance speed and gliding efficiency, they can reduce lift at low speeds and diminish maneuverability in cluttered environments. In contrast, broader wings often provide better low-speed control.
