Pelicans

Pelicans are large birds with large pouched bills. The smallest is the Brown Pelican (P. occidentalis), small individuals of which can be as little as 2.75 kg (6 lb), 106 cm (42 in) long and can have a wingspan of as little as 1.83 m (6 ft). The largest is believed to be the Dalmatian Pelican (P. crispus), at up to 15 kg (33 lb), 183 cm (72 in) long, with a maximum wingspan of nearly 3.5 m (11.5 ft). The Australian Pelican has the longest bill of any bird[1].


Pelicans swim well with their short, strong legs and their feet with all four toes webbed (as in all birds placed in the order Pelecaniformes). The tail is short and square, with 20 to 24 feathers. The wings are long and have the unusually large number of 30 to 35 secondary flight feathers. A layer of special fibers deep in the breast muscles can hold the wings rigidly horizontal for gliding and soaring. Thus they can exploit thermals to commute over 150 km (100 miles) to feeding areas.
