The Dalmatian pelican (Pelecanus crispus) is the largest member of the pelican family, and perhaps the world's largest freshwater bird, although rivaled in weight and length by the largest swans. They are elegant soaring birds, with wingspans that rival that of the Great albatrosses, and their flocks fly in graceful synchrony.
Dalmatian pelicans have stunning silvery-white plumage during the breeding season, which contrasts with the orange-red rubbery pouch beneath its bill and the purple-to-yellow bare skin around its eyes. On their napes, the birds have a thick silver crest of feathers. Over the breeding season, their pouches fade to a yellow color, and in winter their plumage loses its sheen of silver and appears whitish or gray instead. The bare skin around their eyes can vary from yellow to purplish in color.
The range of Dalmatian pelicans ranges 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. The birds usually migrate short distances with varying migration patterns during the year. Dalmatian pelicans are found in lakes, rivers, deltas, and estuaries. They usually return to a traditional breeding site year after year unless it becomes completely unsuitable. During the winter, Dalmatian pelicans usually stay on ice-free lakes in Europe or jheels (seasonal lakes) in India. They also visit, typically during winter, inshore areas along sheltered coasts for feeding.
These pelicans are social birds and live and travel mainly in flocks. On land, they are not graceful, but they fly well and swim strongly. When flying, they rest their heads on their shoulders with their bills resting on their folded necks, and usually, they need to flap their wings only once or twice each second. They are diurnal birds, sleeping at night with heads twisted back, tucked into their feathers.
All species of pelican are careful groomers, and a large part of an individual’s time is spent resting or preening. An individual will clean itself through splash bathing, preening, and rubbing its head over its body to help distribute waterproofing oil through its feathers. Dalmatian pelicans often hunt alone or in small groups. They normally swim along, placidly and slowly, until they quickly dunk their heads underwater and scoop the fish out, along with great masses of water. They are nomadic outside of the breeding season, traveling some distance in search of food. Dalmatian pelicans are often silent, as most pelicans tend to be, although they can be fairly vocal during the mating season, when they may engage in a wide range of guttural, deep vocalizations, including barks, hisses, and grunts.
