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.

Birds in captivity are often heavier than wild specimens. Migratory birds gain weight before the migratory period but lose weight during handling or temporary captivity. Dead birds tend to weigh less than in life. The weight can vary by 5 to 10%, even during the day. The male emperor penguin loses 40% of its weight during incubation. [12]
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.

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 ...

Blossom-headed parakeets commonly frequent farm edges and rural villages in flocks of 20 to 30 birds, causing damage to agricultural crops. [2] The species was found to be the highest contributor to depredation of marigold crops in a 1994 study in India. The parakeets preferred to feed from flowers near perching sites and away from human ...
