Maximum winter counts from all sites counted for the Wetland Bird Survey in Pembrokeshire.  Data after 2000 includes the Teifi Estuary.

Main wintering sites for this species are the Bosherston Lakes, South Hook Pools, Llys-y-fran and Rosebush Reservoirs and Pembroke Millponds.  Bicton Reservoirs was a major wintering site, but has not been used much by coot since 2000. 

The dramatic decline of the last four seasons reflects the trend across Wales, and Britain as a whole.

The Welsh Bird Report for 2014 suggests there are indications of a severe decline in breeding numbers in several western counties in recent years and wintering numbers have also declined at several sites.
