单词	wingspan
释义	wingspan /ˈwɪŋspan / (also wingspread /ˈwɪŋsprɛd/) noun The maximum extent across the wings of an aircraft or of a bird or other flying animal, measured from tip to tip: an eagle with a wingspan of 7 ft... With their stately stature, wingspreads as broad as eight feet, loud calls, and elaborate courtship dances, cranes are among the most impressive birds in the world. The adult is a pretty moth about 1 inch long with a wingspread of 1 1/2 inches; in its northern range, it may be only 1/2 inch long. Females weigh about 2 pounds with a wingspread of 40 to 46 inches, while a male will weigh in at about 1 ½ pounds and span just 37 to 39 inches, roughly the size of a crow.
