What distinguishes shortwings from longwings?

The correct answer highlights a key aspect of the anatomical and behavioral differences between shortwings and longwings. Shortwings are typically characterized by their body structure, which is not conducive to long-distance flight. This is mainly due to their shorter wings, which provide more maneuverability but less efficiency over extended distances.

In contrast, longwings are adapted for soaring and long-distance travel thanks to their longer wingspans. This allows them to glide over long stretches of territory without expending much energy. Understanding this distinction is crucial for anyone studying avian anatomy and ecology, especially in the context of different hunting and flying strategies.

While the other options touch on various characteristics of birds, they do not accurately capture the fundamental distinction regarding flight capabilities between shortwings and longwings. The ability to soar at high altitudes is more associated with longwings, while feeding habits can vary widely within both groups and are not a defining characteristic of either.
