on birds
Not all birds are made equal. Notable examples are:
• A bald eagle was seen carrying a mule deer fawn weighing 6.8 kg (15 lb.) (Martin, 1987).
Bald eagle female weigh approximately 5.8 kg (12.8 lb), males weigh 4.1 kg (9 lb).
• A harpy eagle of South America was recorded carrying a sloth weighing 5.9 kg (13 lb.) (Martin, 1987).
Female Harpy Eagles typically weigh about 7.5 kg (16.5 lb). Males are smaller. Exceptional harpy eagle females have weighed over 9 kg (20 lb).
Also, some birds (I forgot the names) can eat as much as they weigh in one day.
