Estimates of the body mass of Aepyornis maximus span from around 275 kilograms (606 lb) [20] to 700–1,000 kilograms (1,500–2,200 lb) [16] making it one of the largest birds ever, alongside Dromornis stirtoni and Pachystruthio dmanisensis. [21] [22] Females of A. maximus are suggested to have been larger than the males, as is observed in ...

The largest extant species of bird measured by mass is the common ostrich (Struthio camelus), closely followed by the Somali ostrich (Struthio molybdophanes). A male ostrich can reach a height of 2.8 metres (9.2 feet) and weigh over 156.8 kg (346 lb ...

They are the heaviest and largest living birds, with adult common ostriches weighing anywhere between 63.5 and 145 kilograms and laying the largest ...
The male, at 30 to 37 kg (66 to 82 lb), is smaller than the female, at an average of 58 kg (128 lb), making it the fourth heaviest living bird species after the common ostrich, Somali ostrich and the southern cassowary. [2] These birds measure 149 cm (4 ft 10 + 1 ⁄ 2 in) long and stand 1.5–1.8 m (4 ft 11 in – 5 ft 11 in) in height. [2]
Dromornis planei was a very large flightless bird, similar in height to an ostrich or emu but with a heavier build; the species is however exceeded in size by the largest of these "thunder birds" Dromornis stirtoni. [11] Its bill was curved and deep, the overall size of the head and skull was remarkably large. [10]
