investigated potential AIV spread by Common Teal (Anas crecca) from the Camargue area, in the South of France, across Europe. Based on bird-ring recoveries, local duck population sizes and prevalence of infection with these viruses, we built an individual-based spatially explicit model describing bird

Abstract Mate guarding by males is common in species with long-lasting pair bonds. We tested if the need to guard females affected foraging depth in male teal (Anas crecca), and if they were more vigilant than females when foraging with submerged eyes (preventing monitoring of competing males

Abstract.-A new trematode, Paramonostomum bilqeesae new species. recovered from common teal, Anas crecca L. is described here. The fluke is characterized by having small body with a thin delicate cuticle. Oral sucker terminal, oesophagus relatively short, pharynx absent; ceca long terminate some

invertebrate transports simultaneously in a wintering population of teal (Anas crecca) in the Camargue (southern France). We inspected lower gut (rectum) contents of birds that had been shot (N = 366) and washed birds that had been live-trapped (N = 68) during the winters 2006-2007 and 2007-2008. At least one

of a trade-off decision made by individual birds. In this study, we compared the prenuptial migration routes, distances travelled, and breeding areas of (Eurasian) Teal Anas crecca wintering at two sites of different latitudes in western Europe, namely

An avian influenza virus strain, A/domestic green-winged teal/Hunan/2036/2007(H3N6) (DGW-T2036), was isolated from healthy domestic green-winged teals (Anas crecca) in Hunan Province, South China. All eight gene segments of the isolate were sequenced. Genomic analysis demonstrated that this H3N6

and prevernal seasons, constancy and their status of conservation are analysed in the paper. There are two overdominant species among those studied in the hiemal aspect: Anas platyrhynchos and Aythya ferina (both of them found favourable condition for food and shelter here), Anas crecca and Aythya fuligula
