TL;DR: Migration of various species of waterfowl toward the northern parts of Iran has an important impact on parasitic diseases in birds and human in these regions.
Abstract: BACKGROUND: Protozoa are common in poultry and otherbirds and can cause mild to severe disease. OBJECTIVES: Thisstudy was concerned with the prevalence of parasitic protozoa inwild waterfowl in Caspian sea lagoons in the North of Iran.METHODS:Atotal of 293 waterfowl belonging to various generaincluding Tadorna tadorna (common shelduck),Aythya fuligula(Tufted duck), Aythya ferina (Common puchard), Spatulaclypeata (Shoveler), Anser anser (greylag goose), CygnusCygnus (Whooper Swan), Anas strepera (Gadwall), AnasPenelope (Eurasian Widgeon), Anas crecca (common teal), andAnas platyrhynchos (mallard) were sampled and tested forintestinal, tracheal, and blood protozoa between winter 2010 andspring 2011. RESULTS: The results showed that 184 birds of 293(62.8%) harbored protozoan parasites. The highest prevalence ofprotozoan contamination belonged to Giardia spp (24.2%) andthe lowest belonged to Haemoproteus spp. (6.1%). Thricomunasgallinea, Plasmodium spp., and Cryptosporidium spp. werefound in 7.2%, 8.2%, and 17% of waterfowl, respectively.Moreover, statistical analyses showed that the highest rate ofgiardiosis was in female Aythya fuligula (43.75%). However,tricomuniasis belonged to Anas crecca (30.5%). On the otherhand, female Cygnus cygnus had the highest rate ofcryptosporidiosis (44.7%), and more infection to Haemoproteusand Plasmodium spp. were observed in Anas platyrhynchos,concurrently. CONCLUSIONS: Migration of various species ofwaterfowl toward the northern parts of Iran has an importantimpact on parasitic diseases in birds and human in these regions.

TL;DR: It is likely that the recent changes in numbers and distribution of certain wildfowl species have been resulted in partly by climatic factors.
Abstract: The long-term changes in numbers and distribution of 13 wildfowl species breeding and staging in Lithuania were analysed. Three species of wildfowl (Tufted Duck Aythya fuligula, Common Pochard Aythya farina and Goosander Mergus merganser) became established in Lithuania as new breeding birds in the late 19th century and 3 other species (Whooper Swan Cygnus Cygnus, Common Shelduck Tadorna tadorna and Gadwall Anas strepera) did so during several past decades in the 20th century. Marked changes in numbers and distribution of migratory wildfowl populations were recorded during the last decades. It is likely that the recent changes in numbers and distribution of certain wildfowl species have been resulted in partly by climatic factors.

TL;DR: Faecal analysis indicated that the diet of Shelduck feeding in the soft sediments of Aiguillon Bay and Marennes-Oleron Bay was composed mainly of small invertebrates, primarily the mudsnail Hydrobia ulvae, however, the presence of plants and other invertebrate in the diet indicated that they also exploited food resources in adjacent saltmarshes.
Abstract: Common Shelduck Tadorna tadorna were studied in western France, at two wintering sites of international importance for this species. The numbers, densities, feeding activity, feeding methods and diet of Shelduck feeding in the soft sediments of Aiguillon Bay and Marennes-Oleron Bay, on the Charente-Maritime and South Vendee coast, were examined. The birds spent 60% of their time feeding. Prey were obtained mainly by Shelduck moving their bills in a scything action through the mud and sieving small organisms < 8.0 mm long from the upper two centimetres of the surface. Faecal analysis indicated that the diet was composed mainly of small invertebrates, primarily the mudsnail Hydrobia ulvae. However, the presence of plants and other invertebrates in the diet indicated that they also exploited food resources in adjacent saltmarshes.
