[12] [13] For comparison, the living bird with the largest wingspan is the wandering albatross, averaging 3 m (9 ft 10 in) and spanning up to 3.7 m (12 ft 2 in). When grounded, Argentavis' height has been estimated at 1.5 to 1.8 m (4 ft 11 in to 5 ft 11 in), roughly equivalent to that of an adult human. Furthermore, its total length (from bill ...
The majority of this length is due to the hummingbird's extreme tail streamers. Another size champion among hummingbirds is the sword-billed hummingbird, a fairly large species of which approximately half of its 21 cm (8.3 in) length derives from its bill. This is by far the largest bill-to-body-size ratio of any bird. [66]
Size comparison of some phorusrhacids, including Kelenken, Devincenzia, Phorusrhacos, and Titanis. The neck can be divided into three main regions. In the higher regions of the neck, the phorusrhacid has bifurcate neural spines (BNS), while it has high neural spines in its lower regions. This suggests that the phorusrhacid had a highly flexible ...
The Andean condor is the largest living land bird capable of flight if measured in terms of average weight and wingspan, although male bustards of the largest species (far more sexually dimorphic in size) can weigh more. [14] [19] [20] The mean wingspan is around 283 cm (9 ft 3 in) and the wings have the largest surface area of any extant bird ...
This is the world's largest living heron (the extinct Bennu heron was larger). [3] The height of the goliath heron is 120–152 cm (3 ft 11 in – 5 ft 0 in), the wingspan is 185–230 cm (6 ft 1 in – 7 ft 7 in) and the weight is 4–5 kg (8.8–11.0 lb).
Birds figure throughout human culture. About 120 to 130 species have become extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry.

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 ...
