🔍 What makes birds endothermic and homeothermic
🪶 Types of feathers and their roles: insulation, flight, waterproofing
🏗️ Specialized body structure: streamlined body, keeled sternum, hollow (pneumatic) bones
🍽️ Digestive tools: the crop (temporary food storage) and gizzard (mechanical grinding)
💨 Respiratory system: air sacs, one-way airflow through parabronchi, efficient gas exhange
🎶 Vocal organ: the syrinx, enabling diverse bird calls and songs

🏃♀️ Examples:
Running (flightless) birds: ostrich, emu, rhea, kiwi, cassowary
Flying birds: eagles, parrots, pigeons
