This page presents information on recoveries of Mallard that have been ringed or recovered in Britain & Ireland. The table summarises the number of birds that have moved between different counties of Britain & Ireland and between other countries and then gives a selection of recoveries. First are listed the number of birds found in each county, then the number of birds ringed in each county. In the next two columns are listed the number of birds ringed abroad and found in Britain & Ireland and the then number of birds ringed in Britain & Ireland and found abroad. NOTE: Some older records (mostly pre-1979) of foreign ringed birds recovered have not been computerised so these will not appear in the table. We aim to add them in due course.

A selection of recoveries are given in full because they represent particularly long-lived birds (the national longevity is indicated with a link to details of this record), birds which have moved a long distance within Britain and Ireland, birds which have gone to, or come from countries with few such recoveries, or because few birds of this species have been recovered. For birds that have moved more than 20km a link is provided to a map showing ringing and finding locations. Ringing location is marked by a blue (R), finding locations are numbered in sequence. If there are more than ten finding locations, subequent markers will be labelled (x). Finding markers are coloured red for birds found dead and green for birds seen alive, for those where this is not known the marker will be white. NOTE: If a bird is found multiple times at the same site only one marker will be visible, though a darker shadow to the marker will indicate the presence of more than one recovery at that location.

For longevity and distance records an individual is only included once, for reports to and from countries an individual may be reported multiple times, particulary if it bears a colour mark or other means of identification in the field.
