The eight living pelican species were traditionally divided into two groups, one containing four ground-nesters with mainly white adult plumage (Australian, Dalmatian, great white, and American white pelicans), and one containing four grey- or brown-plumaged species which nest preferentially either in trees (pink-backed, spot-billed and brown ...
Reviewing genetic evidence to date, Cracraft and colleagues surmised that pelicans were sister to the shoebill with the hamerkop as the next earlier offshoot. [7] Ericson and colleagues sampled five nuclear genes in a 2006 study spanning the breadth of bird lineages, and came up with pelicans, shoebill and hamerkop in a clade. [8]
This huge bird is by a slight margin the largest of the pelican species and one of the largest living flying bird species. It measures 160 to 183 cm (5 ft 3 in to 6 ft 0 in) in length, 7.25–15 kg (16.0–33.1 lb) in weight and 245 to 351 cm (8 ft 0 in to 11 ft 6 in) in wingspan.

American white pelicans gathering at Pelican Island National Wildlife Refuge in Florida. Brown pelicans can also be seen in the center, and at the left and right margins. With wings spread, showing black remiges. The American white pelican rivals the trumpeter swan, with a similar overall length, as one of the longest birds native to North ...
The brown pelican is the smallest of the eight extant pelican species, but is often one of the larger seabirds in their range nonetheless. [15] [16] It measures 1 to 1.52 m (3 ft 3 in to 5 ft 0 in) in length and has a wingspan of 2.03 to 2.28 m (6 ft 8 in to 7 ft 6 in). [6]
The Australian pelican is not globally threatened. They are usually fairly common in proper habitats. At the aforementioned temporary inundation of Lake Eyre in March 1990, over 200,000 adult birds were found to be breeding. The species is legally protected and does not seem to be showing any immediate adverse effects from pollution.
Sixty-six (66) animal species are listed in the Vietnam's Red Data Book and 23 other species in the World Red Book of Endangered Species. In 2005, a new species of gecko ( Lygosoma boehmeiwas ) was discovered here by a group of Vietnamese biologists together with biologists working for the park, Cologne Zoo in Germany and the Saint Petersburg ...
