The largest species of this order of nocturnal birds is the neotropical great potoo (Nycitbius grandis), which can grow to a weight of 680 g (1.50 lb) and a height of 60 cm (2.0 ft). Heavier Caprimulgiformes have been recorded in juvenile specimens of the Australian tawny frogmouth ( Podargus strigoides ), which can weigh up to 1.4 kg (3.1 lb).
Most species survive upwards of 50 years, the oldest recorded being a Laysan albatross named Wisdom that was ringed in 1956 as a mature adult and hatched another chick in February 2021, making her at least 70 years old. She is the oldest confirmed wild bird and the oldest banded bird in the world. [38] [39]
This list is incomplete, because experts have not estimated all bird numbers. For example, the spectacled flowerpecker was only discovered in 2010, and did not receive its scientific name ( Dicaeum dayakorum ) until 2019, [ 4 ] adding to the other 73 new bird species described by ornithologists from 2000 – 2009.

The snowy albatross has the longest wingspan of any living bird, reaching upwards of 3.5 m (11 ft), [12] [13] with a mean span of 3.1 m (10 ft 2 in) in Bird Island, South Georgia. Wingspan measured an average of 3 m (9 ft 10 in) in 123 birds measured off the coast of Malabar, New South Wales .
The bill measures 10.5–12 cm (4.1–4.7 in), up to twice the length of a Canada goose (Branta canadensis) bill; the trumpeter swan bill is the largest of any waterfowl species in the world. The legs are gray-pink in color, though in some birds can appear yellowish gray to even black. The tarsus measures 10.5–12 cm (4.1–4.7 in).

More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.
