A survey on water birds fauna in Dez Protected Area in Khuzestan province

In this survey investigated water birds fauna in Dez Protected Area in Khuzestan province in 1392. This study is one of the most initial studies in this area. It identified 33 species of birds that concerned to 6 orders and 13 families. Numbers were estimated 10 water birds and 23 shore birds that was including %6.5 of total species, %17.5 of total families and %21 of total orders of declared species in Iran. In this survey, observed species dedicated to %21 species, %54 of families and%85 of orders into Iran water birds. In studied area identified 9 endemic species, 23 migratory species, 3 semi migratory species and 2 crossing migratory species. Also 15 species were seen in all seasons and just 4 species for one season. To observation of bird fauna in Iran showed that species richness was enough high in studied area. In spring attended 26 taxa, summer and winter 25 taxa and autumn 21 taxa. The most frequency of bird's observation in studied area was in winter and the least frequency was in summer. Based on results Dez Protected Area supported abundant species during a year. To observation of rare and world endangered species like as Marbled teal(Marmaronetta angustirostris, Ferruginous Duck (Aythya nyroca) and Socotra Cormorant(Phnlacrocorax nigrogularis) and also species that are faced to declining of population like Pygmy Cormorant(Phalacrocorax pygmeus) and other species implicated to importance of this habitat and locating on world important birds migration routes. So that present survey is a primary study about Dez Protected Area's bird fauna and because of equality of species richness in year it suggests to do detailed study in order to birds monitoring during a year.
