Great eds have little eds upon their backs to bite 'em,
And little eds have lesser eds, and so ad infinitum.
And the great eds themselves, in turn, have Admin eds to go on;
While these again have greater still, and greater still, and so on.

The Dalmatian pelican (Pelecanus crispus) is a bird in the family Pelecanidae. With a length of 160 to 183 centimetres (63 to 72 inches), a mass of 7.25 to 15 kilograms (16.0 to 33.1 pounds) and a wingspan of 245 to 351 centimetres (96 to 138 inches), it is the largest pelican species and one of the world's largest living flying birds. The Dalmatian pelican has a range spanning across much of central Eurasia, from the Mediterranean in the west to the Taiwan Strait in the east, and from the Persian Gulf in the south to Siberia in the north. It is a short-to-medium-distance migrant between breeding and overwintering areas. The Dalmatian pelican's preferred habitat is lakes, rivers, deltas and estuaries, and it feeds on various fish species such as the common carp and European perch. Like many pelicans, it is often silent, but can be vocal during the mating season, engaging in a wide range of guttural, deep vocalisations, including barks, hisses and grunts. This Dalmatian pelican was photographed in flight over the Danube Delta in Romania.
