Among a highly social family in general, Dalmatian pelicans may have the least social inclinations. This species naturally nests in relatively small groups compared to most other pelican species and sometimes may even nest alone. However, small colonies are usually formed, which regularly include upwards of 250 pairs (especially historically).
The Pelecaniformes / p ɛ l ɪ ˈ k æ n ɪ f ɔːr m iː z / are an order of medium-sized and large waterbirds found worldwide. As traditionally—but erroneously—defined, they encompass all birds that have feet with all four toes webbed.
Many studies have looked at the effect of sociality on the brain development, mostly focussing on non-human primate species. In primates, it has been shown that relative brain size, when controlling for the size of the species and the phylogeny, seemed to correlate with the size of the social group. [1]
Social behavior requires individual identification, and most birds appear to be capable of recognizing mates, siblings, and young. Other behaviors such as play and cooperative breeding are also considered indicators of intelligence. Crows appear to be able to remember who observed them catching food. They also steal food caught by others. [55]
The great white pelican is a huge bird—only the Dalmatian pelican is, on average, larger among pelicans. It measures 140 to 180 cm (55 to 71 in) in length [ 6 ] with a 28.9 to 47.1 cm (11.4 to 18.5 in) enormous pink and yellow bill , [ 6 ] and a dull pale-yellow gular pouch.
The spot-billed pelican is a rather large water bird, often the largest or one of the largest native birds in the southern stretches of its range, albeit it is fairly small for a pelican. It is 125–152 cm (49–60 in) long and a weight of 4.1–6 kg (9.0–13.2 lb).

The American white pelican rivals the trumpeter swan, with a similar overall length, as one of the longest birds native to North America. Both very large and plump, it has an overall length of about 50–70 in (130–180 cm), courtesy of the huge beak which measures 11.3–15.2 in (290–390 mm) in males and 10.3–14.2 in (260–360 mm) in ...
