List of largest birds
The largest extant species of bird measured by mass is the common ostrich, closely followed by the Somali ostrich. A male ostrich can reach a height of and weigh over, A mass of has been cited for the ostrich but no wild ostriches of this weight have been verified. Ostrich eggs are the largest of any bird, averaging.
The largest wingspan of any extant bird is that of the wandering albatross of the Sub-Antarctic oceans. The largest dimensions found in this species are an approximate head-to-tail length of and a wingspan of.
The largest bird of all time was likely the elephant bird Aepyornis maximus, which was estimated to have weighed and stood at tall.
The largest wingspan of all time likely belonged to Pelagornis sandersi at roughly 5.2 m. P. sandersi was also likely the largest bird to ever fly.

Table of heaviest extant bird species
The following table is a list of the heaviest extant bird species based on maximum reported or reliable mass, with the average weight is also given for comparison. These species are almost all flightless, having denser bones and heavier bodies. Flightless birds comprise less than 1% of all extant bird species.By order">Order (biology)">order

- The longest hummingbird species, indeed the longest in the order, is the adult male black-tailed trainbearer, which can measure up to. 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 length derives from its bill. This is by far the largest bill-to-body-size ratio of any bird.

The largest species of pelican on average is the Eurasian Dalmatian pelican, which can attain a maximum length of, a body weight of and a wingspan of. Although the males of great white pelican of Eurasia and Africa are heavier on average than the males of Dalmatian pelicans but due to a greater degree of sexual dimorphism in great white pelican than any other pelican species it averages slightly lower than Dalmatian pelican as the females of latter are larger and heavier on average than those of the former. The maximum wild mass for a pelican as given in scientific literature is only recorded for male great white pelican while the next maximum masses are and for American white pelican and Australian pelican respectively, here the latter figure being exactly the same as the maximum mass of Dalmatian pelican which is larger on average than both of these North American and Australian species. The Australian pelican as already stated is slightly smaller but has the largest bill of any bird, at as much as long and the maximum length of for this species is the maximum among all the pelicans even exceeding the maximum length of Dalmatian pelican which is generally regarded as the longest pelican as per many field guides and scientific literature. The great white pelican and dalmatian pelicans are known to have the next longest avian bills with maximum recorded lengths being 47.1 cm and 45 cm respectively.
