The long-tailed parakeet was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux. [2] The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.

Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species, dimensions may vary across populations within species, between the sexes and depending on age and ...
The feet in loons [2] and grebes [2] [7] are placed far at the rear of the body - a powerful accommodation to swimming underwater, [7] but a handicap for walking. The snowshoe-like foot of the willow ptarmigan is an adaptation for walking on snow. [1] Because avian forelimbs are wings, many forelimb functions are performed by the bill and ...
The jandaya parakeet is a small, long-tailed parakeet with the reddish-orange body, green wings, vent and tail, yellow head, neck, and shoulders, orange cheeks, black bill, whitish periophthalmic ring, and dark eyes. The ends of the tail feathers are tinged in blue. It measures 30 cm (12 in) in length and weighs 125–140 gm.
The largest dimensions found in this species are an approximate head-to-tail length of 1.44 m (4.7 ft) and a wingspan of 3.65 m (12.0 ft). The largest bird of all time was likely the elephant bird Aepyornis maximus, which was estimated to have weighed 275–1,000 kilograms (610–2,200 lb) and stood at 3 metres (9.8 ft) tall. [4] [5]
The largest parrot by length in the world, the hyacinth macaw is 1 m (3 ft 3 in) long from the tip of its tail to the top of its head and weighs 1.2–1.7 kg (2 lb 10 oz – 3 lb 12 oz). [11] [12] Each wing is 38.8–42.5 cm (15 + 1 ⁄ 4 – 16 + 3 ⁄ 4 in) long. [11] The tail is long and pointed. [11] Its feathers are entirely blue, lighter ...
The entire length of the tail was about 3.5% as long as the wingspan, or up to 25 cm (9.8 in) in the largest males. [ 24 ] Pteranodon 's scapulae were oriented in such a way that each one braces the other, due to their fusion with the coracoids , providing increased integrity during flight. [ 26 ]
Size comparison between a human and two species of Basilosaurus, B. cetiodes (dark blue) and B. isis The heaviest archeocete , and possibly the heaviest known mammal was Perucetus , with weight estimated at 85–340 t (84–335 long tons; 94–375 short tons), while length is estimated at 17.0–20.1 meters (55.8–65.9 ft), [ 108 ] possibly ...
