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 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.

First described by French naturalist Anselme Gaëtan Desmarest in 1826, the superb parrot is one of three species in the genus Polytelis of long-tailed parrots. [4] Common names include superb parrot and, in avicultural circles, Barraband's parrot or parakeet, named after the artist Jacques Barraband who illustrated it for Francois Le Vaillant in 1801 [5] or green leek (although the last is ...
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 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 ]
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 ...
While they can prey on various sizes of fish from small fingerlings to large adult fish, measuring 60 cm (24 in) in length and weighing around 900 g (2.0 lb), small to medium-sized fish around 10–20 cm (3.9–7.9 in) are usually preferred.
With a length of 4.3 inches and a weight of 0.18-0.21 ounces, the American Bushtit is one of the smallest passerines in North America. It is mostly gray-brown in color, with a large head, short neck, long tail, and small, stubby beak. Moreover, bushtits have different characteristics based on their sex and habitats. The male has dark brown to ...
