Australian Pelican
Pelecanus conspicillatus
The Australian pelican is medium-sized by pelican standards, with a wingspan of 2.3 to 2.6 m (7.5 to 8.5 ft). Weight can range from 4 to 13 kg (8.8 to 28.7 lb), although most of these pelicans weigh between 4.54 and 7.7 kg (10.0 and 17.0 lb). The average weight of four unsexed Australian pelicans was 5.5 kg (12 lb), making this the second heaviest Australian flying bird species on average, after the brolga, although the male of the more sexually dimorphic Australian bustard weighs a bit more at average and maximum weights (both birds are, of course, much smaller than the cassowary and emu).

Spot-billed Pelican
Pelecanus philippensis
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 wingspan can vary from 213 to 250 cm (7 ft 0 in to 8 ft 2 in) while the typically large beak measured from 285 to 355 mm (11.2 to 14.0 in). It is mainly white, with a grey crest, hindneck and a brownish tail. The feathers on the hind neck are curly and form a greyish nape crest.
