A new exploratory approach to the study of the spatio-temporal distribution of ring recoveries: the example of teal (
Anas crecca) ringed in Camargue, southern France.--J.
We collected 19 H5N8 viruses from 16 common teals (
Anas crecca), 2 falcated ducks (A.
It is noted that during the period of wintering, the ducks mallard cohabit with other aquatic species such as the Gadwall (Anas strepera) birds, the Eurasian Coot (Fulica atra), the Great Cormorant (Phalacrocorax carbo), the Eurasian Teal (
Anas crecca), the Common Moorhen (Gallinula chloropus), the Great Crested Grebe (Podiceps cristatus) and the Little Grebe (Tachybaptus ruficollis).

In middle wintering stage (from December to February), the sex ratio of common teal
Anas crecca (60.66% male, n=361) was male-biased while falcated duck Anas falcata (52.10%, n=286), mallard Anas platyrhynchos (50.00%, n=90) and Eurasian wigeon Anas penelope (49.18%, n=183) were near parity.
(2009) found that the Mediterranean wetland of Camargue offered teal
Anas crecca more seed food than any studied site of northern Europe.

Of the 2 migratory birds positive for the H5 gene, the first was a common teal (
Anas crecca) captured in the Nile Delta region of Damietta in October 2005 (online Appendix Figure, panel A).
The aim of our study was to quantify the extent to which such switches between day roosts occur, by means of resightings of nasal-saddled teal
Anas crecca. Such definition of the scale at which habitat selection occurs in wintering ducks may obviously be useful in terms of wetland management policies.
