Order Pelicaniformes

The Pelicaniformes currently contain the pelicans (Pelecanidae), herons (Ardeidae), spoonbills and ibises (Threskiornithidae), Hammerkop (Scopidae), and shoebill (Balaenicipitidae). This order may need to be separated into additional orders as the similarities of these families may be due to convergent evolution and not common ancestors.


 Pelecanidae Family -  Pelicans And Allies


The pelicans, which belong to the Pelecanidae family, are large waterbirds found worldwide. They primarily inhabit warm regions. The diet of a Pelican consists mainly of fish. They often catch the fish by expanding the throat pouch which must be drained above the surface before they can swallow. They can cool themselves by panting and fluttering their pouch. Pelicans swim well with short, strong legs and feet that have four webbed toes. A layer of special fibers deep in the breast muscles can hold the wings rigidly horizontal for gliding and soaring.

There are eight species of pelicans. Some species catch fish while swimming, while others mainly catch fish by diving from their flights. The males are larger than the females, but they are not differentiated by their plumage. Some species are mainly white, while others are brown or grey. Some species nest on the ground, others in trees. The preference for ground or tree nesting is a function of species size – the larger ones preferring the ground.

Their dimensions range as follow: length 1.25 to 1.9 m (4.1 – 6.2 ft); wingspan 2.0 to 3.4 m ( 6.6 – 11.2 ft); weight 3.6 to 12 kg (7.9 – 26 lb).


Taxonomy

The Pelecanidae family belongs to the Pelecaniformes order which also includes Ardeidae (herons and egrets) and Threskiornithidae (ibises and spoonbills). There are two other families: Balaenicipitidae (shoebill) and Scopidae (hamerkop). Each of these families only contains one species.

Etymology

The name pelican probably traces back to the ancient Greek eleka which referred to woodpeckers. Woodpeckers are notable for their chisel-like bills while pelicans are noted for their supersized bills.
