Question

لماذا العصفور يطير والديك لا يطير ؟

Answer 1

الديك لا يطير بسبب أجنحته الصغيرة جدا مقارنة بجسمه كما أن عضلات الطيران لديه كبيرة جدا و ثقيلة مما يصعب عليه عملية الطيران ,
فالطيور عادة تحتاج إلى موازنة حجم الأجنحة لديها بشكل مناسب لتستطيع الطيران بحيث يتم توزيع نسبة كتلة الجسم إلى مساحة الجناح .
