An individual mute swan, which may have lost the power of flight due to extreme weight, was found to have weighed 23 kg (51 lb). [17] Meanwhile, the sarus crane is the tallest flying bird alive, at up to 1.8 m (5 ft 11 in) tall, standing about as high as Argentavis due to its long legs and neck. [citation needed]
Sylviornis is an extinct genus of large, flightless bird that was endemic to the islands of New Caledonia in the Western Pacific. It is considered to constitute one of two genera in the extinct family Sylviornithidae, alongside Megavitiornis from Fiji, which are related to the Galliformes, the group containing the turkeys, chickens, quails and pheasants.

Known for its ivory-colored bill, black-and-white markings (the males also sport red), and ability to grow larger than a crow, the last confirmed sighting of the North American bird was back in 1944.

Subfossil remains and remnants of the birds that were brought to Europe in the 17th century show that dodos were very large birds, measuring about 62.6–75 cm (24.6–29.5 in) in height. [37] [38] The bird was sexually dimorphic; males were larger and had proportionally longer beaks. Weight estimates have varied from study to study.

The bird lived in huge, noisy flocks of as many as 300 birds. It built its nest in a hollow tree, laying two to five [ 26 ] (most accounts say two) 1.6 in (4.1 cm) round white eggs. Reportedly, multiple female parakeets could deposit their eggs into one nest, similar to nesting behavior described in the monk parakeet ( Myiopsitta monachus ).
